There might still be brains on this one. It still has brains on it?

(Describer) Something in a cardboard box is blurred. Titles: The Brain Scoop, with Emily Graslie. In a car:

-Oh my gosh! -[laughing] Yes, oh my God! Ooh! -Whoa! -Wow.

[bright upbeat music]

How big are Chicago rats? I am about to go into the oldest pest management company in the United States. I'm excited to get my hands on some answers.

(Describer) Outside a brick building with an old mural of a cartoon exterminator, Emily hugs Rob Scallon. A woman with a red scarf tied around her hair runs out to hug Emily.

Hey! Hi! Yay, it's good to see you!

(both) Hi! -(Rob) Hey. -[Janelle laughing] -How are you? -I'm good, how are you? We're already filming. -Oh, good. -[all laughing]

(Describer) The woman waves, then leads them inside the building.

-[door creaking] -This is awesome. -Rob Scallon? -Yes. [laughing]

(Janelle) Ooh, wow. I have been watching you for years, man. -Wow. -Holy crap, how you doin'? -Oh my God. -But, I wasn't expecting you. Emily asked like, "Hey, do you wanna go pick up some rat carcasses?" I'm like, "Yeah, of course." People are so excited about this. I know. [laughing] I'm Janelle Iaccino, affectionately referred to as The Rat Lady in Chicago.

[Emily laughing]

My title for Rose Pest Solutions is Marketing Director, but it's not just a job; it's a lifestyle. We're going on 19 years in April. -Wow, you are The Rat Lady. -I am The Rat Lady. Outside of Rose too, I'm very connected with the Peggy Notebaert Nature Museum, and I do a lot of rat studies there,

and it's never-ending fun. [laughing]

Livin' and breathin' rats. -Yup. -Are those rat jaws? So these are mink jaws,

(Describer) Her earrings.

another voracious creature that I love. These are my rat earrings.

(Janelle) I always match the flare with the outfit. You have to; it's a whole thing.

(Describer) She also wears rat socks.

We are currently in one of our most historic offices. This has been here since I think the '40s? I don't know if you guys happened to catch the ghost mural on the side of the building. -[bell chiming] -Old-school Bug Man. He's our little icon, and so is the taxidermied rat that gets dressed up in our storefront window.

(Emily) I was noticing that when I walked by. -"We're in the right place." -That thing is ancient. That's been here since the '40s also. And every one of our branches has a taxidermied rat, -the unofficial mascot. -[Emily laughing] There's endless stories. The owner of my company, Robert Dold, a senior, okay, he's about 85 years old now. -Wow. -At one point, he was saving rat pelts to make a coat for his wife who never agreed to wear such a thing, but-- Like, on Christmas morning? -I know, right? -It's like, "Hey honey." The whole family's gathered around-- -She's like... -And he's like, "Put it on!"

[everyone laughing]

It never ended up happening because someone cleaned out the basement and threw away his collection, and he cried for days. -Oh no! -It was devastating for him. So it's been a thing to like [laughing] repopulate his pelt collections-- -Oh my gosh. -So that we can make things out of them. I'm really excited that we can take a couple of these rats and turn them into what I'm hoping to be an epic diorama representing the rat environment in Chicago in 2023. I love it.

(Rob) How long has this company been around? Since 1860. I have old ads that sold boxes of arsenic for 15 cents.

(Emily) Whew!

(Janelle) And it listed all the things that it would kill, except for humans. -It's fascinating-- -That's wild. Like how pest control has evolved over the years. I mean, I've got old ads back in the '40s/'50s of housewives with these giant canisters spraying over their child's crib. The baby's like this in the crib, and they're just, like, gassing for bed bugs like, -"No big deal, guys." -[Emily and Rob laughing] Yeah, we have come a long way since then. I am curious to know, what are you guys doing today? Because we know Chicago's got a rat problem, -New York's got a rat problem. -Right. They have all these connotations of being dirty, -disease carrying. -Yeah.

(Emily) Like, the only solution is to eradicate them entirely. Is that feasible? It hasn't happened yet, has it? How are we gonna live with 'em? Well, I think by raising awareness constantly. When I talk about rats, it's a community effort. It's not just the job of an exterminator; it's not just the job of the city officials, although we love their generous budget that they put out. They've greatly increased their spend on that this year but it's necessary. Nine years in a row for "Rattiest City"? Come on, we have better things to be proud of. Ooh. -Right? -I didn't know that. -For us to beat New York-- -Sick. Is just kind of like, "What?" But we have alleys; they don't have alleys. We have a lot more places for rats to hide. And when they're not feeding, they're breeding.

(Emily) Rats are living it up in Chicago. But that's the thing, rats are one of those creatures that will thrive on human error. Every time you don't pick up after your dog, you're puttin' out a buffet for the rats. -Ew. -Every time you leave your garbage on your second-floor balcony instead of bringin' it down to the dumpster, you're inviting them on up. -Oh no. -So, it's gotta be a collective effort. One of the most important things that I tell people is if you notice signs, use the 3-1-1 app, report it. Because that's how the City dispatches their abatement team. Ooh, I didn't think-- The more concentration of reports in a certain area, that's how they dispatch 'em. I thought 3-1-1 was just like call before you dig kinda thing. That's JULIE, 8-1-1. -Oh man, I don't know anything! -[Janelle and Rob laughing] I'm gonna be calling every number, 9-1-1, 4-1-1, being like, "We got rats, what do I do? -I need help." -3-1-1. [laughing] I have a lotta cat lady friends. One of them used to work for the Tree House Humane Society. They rent feral cats to homeowners, residents in Chicago, to control rat populations too. And it's not the cats that are eating them, they're just urinating and marking a territory -to ward their prey off-- -Ooh. Because rodents have an exceptional sense of smell. They actually have a nose inside their nose, -which is really fascinating. -Really? [laughing] But it's like extra-sensory nose capabilities. And if they smell predatorial urine, they're not gonna want to be in that area. You're using captured feral cats-- Yeah. Nature against nature, and I love that stuff. -Yeah. -But they're rented out, like, you can't get any more feral cats. Is there like a Blockbuster or library service, and you're like, "I was really waiting for Mr. Whiskers, but he's booked for the next three weeks?" And of course my like weird mind always goes to like, "Well if it's cat urine, can we just get a bunch of it, -and then homeowners..." -Actually... -We got a lot at our house. -Yeah? If you've ever been inside of a Farm and Fleet, they sell coyote urine by the jug, which people have used for rabbit control in rural settings and things like that. -Yeah. -That would work too. Coyotes are making a comeback in Chicago. They are appearing more frequently along the lakefront paths. Between the rabbits, and the squirrels, and the rats, like it's a smorgasbord. What I'm hearing is Chicago is like actually a really great place for wildlife. Yeah. Some of the things that I take personal interest in is like, okay, what are birds of prey patterns looking like? Because they are also natural predators of rodents. If there's more rats, you're gonna start seeing more Cooper's hawks -and more owls. -Ooh yeah.

(Janelle) And that's been happening. You have to find the source and curb the problem at the beginning of it, and that's human behavior issues, it's staff issues. If you have a restaurant, and you got people smokin' cigarettes out the back with the door propped open-- It's like a whole behavioral thing. That's why you hire a professional, too, is 'cause we go through all that stuff and teach them these things so that they're aware of it. I really wanna see some of these rats. Should we glove up and go check 'em out? -I think so. -(Rob) That's why I'm here. Here's my stack of rats that I've been collecting for you guys

(Describer) Outside:

over the course of the last week. I thought these were just like a doorstop. These are nicely bagged with data, and they have all come from various locations. -Oh, okay. -(Rob) Oh boy. There's weather information on there too. They're all very intact ratsicles. Because of sub-zero temperatures, we will often find intact rats just dead inside of our stations 'cause they're trying to seek shelter out of the elements. It's kind of a question, did it eat the rodenticide or did it just freeze? That's up to you to find out when you dive in. When you open the stomach contents, if it's turquoise, that means it got into the rodenticide. If it's normal colored, it could have been snapped in a trap, which is how some of these other ones got captured too. Like usually it's the back of the neck, so if there is skull damage, I apologize. I mean, the name of the channel is "The Brain Scoop." Yeah, you're right. So that is okay. There might still be brains on this one.

(Describer) She gets the box.

It still has brains on it? -Oh my God! -[laughing] Yes, oh my God!

(Describer) Inside is a rat carcass with a crushed abdomen.

Ooh! -Whoa! -Wow.

(Janelle) So that's the little gnarly one, but this is a juvenile--

(Rob) Is that barbecue sauce?

(Describer) "Is that barbeque sauce?"

-Nope, definitely not. -[Emily laughing] How many parasites live on these things? You're talkin' ticks, fleas, over 32 viruses and bacteria that they carry. Salmonella, E. coli are the ones we all know, all the other unpronounceable Latin names. I mean, you can look up the list on CDC if you want. This is why they're a public health threat. It sucks because I love animals as much as the next guy, but this kind of animal is not the pet rat that you're gonna buy in a Petco. I have no idea what this bag is gonna be like; I'm opening it. This is like unboxing, only--

[Emily and Rob laughing]

(Describer) Wearing gloves as they all do, she opens a small garbage bag.

This is my version of unboxing. [laughing] "This is the Christmas present I got?" -"Thanks, Mom." -Sometimes, it's... Okay, so this is a bunch of trash, but guess who's in here along with the trash?

[Emily laughing]

(Describer) She digs through it. She holds a carcass with colored powder on it.

Oh man, hang on. -There he is. -(Emily) Oh man, there we go.

(all) Whoa. Okay, so this turquoise color, that's the rodenticide. This is the most humane rodenticide that is accessible to professional pest controllers, and it's just meant to kill them very quickly so that they're not contaminating other wildlife. Secondary poisoning is very much a concern, especially because we have a million customers with pets. So this guy is your average, I'd say. I mean, the ones that I've been catchin' lately have been between 10 and 15 inches tip to tail. -(Emily) Okay. -Which is intimidating. You've taxidermied rats before, right? No, I've never taxidermied a rat. Oh my gosh, the most satisfying thing about taxidermying a rat is the tail. Because once you get down there, it just slips right off.

[Rob laughing]

It's like a straw, right, coming out of the rat? Yes. This thing totally has ticks on it. -There's one right there. -Oh, yeah.

(Describer) ...on the underside.

-(Rob) Oh, gross. -(Emily) Oh, those are tiny. They're teeny-tiny, like pinhole, but that's what lives in rat burrows. -(Rob) Wow. -It's such an ecosystem. It's fascinating, like rats live off of our human error, but then look at all the things living on the rat. -Yeah. -It's endless. And there always has to be a balance. And the balance is upset right now because these things are thriving. We're not trying to wipe out a species in general with anything, but it's important to keep everybody safe. Yeah.

(Describer) Rob:

I hadn't thought of the ticks, that that would be part of it. Ticks has gotta be like my least favorite organism. -Ticks, yup. -Yeah.

(Janelle) It's creepy in an urban setting too. 'Cause normally when you think of ticks, you're like, "Oh, you've been out in a forest preserve," or, "You've been hiking," or whatever. No, they're all over the city, in alleys too, because of these things. People are gonna be so itchy watching this. Is there one on your back? I'm not really sure, maybe go check. Are you gonna want this whole trash habitat? Yeah, yeah, why not? Because this is research for me. -I know, right? [laughing] -No, really. Becky Stern, my friend comin' from New York with her own background on rat stuff, and we're making this diorama. I want it to be as accurate as possible -to their habitats. -Oh my goodness. I love the Taco Bell wrappers in here. Me and the rat have a similar diet. -Fourth meal. -Not a sponsor! Not a sponsor. But aw, if they wanted to sponsor any of my videos, Taco Bell, let me know.

(Rob) There ya go, bud.

(Describer) They pack all the bags.

-There you go, buddy. -And I wanna come back out and show you guys this piece of equipment -because I think-- -Oh yeah.

(Describer) Janelle walks away past Emily and Rob, who takes a step back.

-Ugh. -Let's see. Sorry. [laughing] -Are you okay? -[Rob cringing] -(Janelle) Actually-- -[coughing] I'm good.

[Emily laughing]

(Describer) He turns away. Emily holds the box with the crushed carcass.

You need a minute?

[Emily and Rob laughing]

-(Rob) It's the bar... -(Janelle) I can untarp it. I don't know exactly how this used to work. Are you alright, Rob? -Sorry, yeah, I'm good. -Sorry, are you alright? -Did you just yak? -No, I'm good, -it's just the barbecue sauce. -Oh yeah. Okay, let me go get a bag.

(Emily) The thing about this is nobody put me up to this. Nobody was like, "Emily, I really wanna get your perspective on this." I was like lookin' for the person where I could source some rats, I picked this. -This is... -I chose this.

[Rob laughing]

Somehow uploading YouTube videos got us here, you know? I know.

(Describer) Janelle puts the carcass in a bag.

-There we go. -There you go.

(Emily) That looks so much better now.

(Cameraperson) Hey, bud.

(Rob) Do you name them? Nope, I'm not that sentimental with these guys. Are there even that many names? The Taco Bell one, -I mean, you could really go-- -Yeah. You could go like "Chalupa." You gonna taxidermy Chalupa? "That one likes to party and eats Taco Bell"? Yeah.

(Janelle) I wanted to show you some of the old equipment that we used to use. We have some old rodenticide mixers in our corporate office. Back in the '60s and '70s, they used to take a loaf of white bread, a jar of peanut butter, and a can of arsenic--

[Emily and Janelle laughing]

(Describer) Title: Death Sandwich.

And then that's how they would kill the rats.

(Emily) What is happening here? I am pretty sure this was a typewriter.

(Rob) What did the typewriter have to do with killing rats?

(Janelle) I have to look this up.

(Emily) This is where you write the ransom note.

(Describer) Beside it:

This machine is what they used to use to mix up chemicals. It kinda looks like a bakery stand mixer.

(Rob) And was arsenic used with this?

(Janelle) I believe so.

(Emily) So if we sampled the inside of that--

(Janelle) Don't lick it. That's obviously obsolete. We don't do any hand mixing in this facility, everything is packaged from our manufacturers which we work very close with, and the EPA of course approves everything.

(Emily) And this is a little--

(Janelle) Yeah, there's the mixer blade.

(Rob) Ooh, right on.

(Janelle) Anyone wanna make a rat cake?

(Rob) Yeah.

[Rob laughing] I mean, we got the ingredients.

In the museum world, arsenic is used when they used to prepare the specimens too because it would keep all the pests out of the taxidermy. -Right. -Hmm. And then you would have these like museum people who wouldn't retire until they're like 110, and we always joke that the arsenic helped preserve them too. -Yeah. -Oh my gosh. All the formaldehyde in those things. What doesn't kill you makes you stronger. Except for these guys.

(Rob) Yeah, that just killed them. Go back in, and I wanna show you guys upstairs.

(Describer) Upstairs:

(Janelle) These are the landscape bait station rocks, so--

(Emily) Oh, I thought those were brains. -I don't know why. -There's no brains on these.

(Describer) Rob picks up a gray rounded station.

(Rob) Oh, they're heavy. -Yeah, there's weights in 'em. -There's lot of rats in 'em? They come pre-ratted. All of our stations are weighted so that they don't carry the station off if they get stuck in them, which has happened. I now bet I will start seeing these all over the place, now that I know to look for 'em.

(Emily) Oh yeah, I see them everywhere, especially along like grocery stores, -like the perimeter of grocery stores. -Yes.

(Janelle) These are the ones that we most commonly use, and our staff kind of pre-baits them and gets them ready.

(Describer) She opens a black station.

There's a weight in the bottom, see?

(Describer) She picks up the bait tray to show them.

(Emily) Okay. So these are designed to where the entries are conducive to what their habits like and what they enjoy. So they detect light, odor, and airflow to determine whether or not it's a safe travel spot. Because their eyesight isn't very good, they typically will stay close to a structure. And so when we place these, the holes are close to that structure. They'll come in and out as they please. Sometimes there's a snapper in here instead of bait, depending on what the environment calls for. You know, maybe there's a lot of dogs in the yard, we'd rather mechanically handle it and physically remove it. Is this appetizing to a rat? Yeah, so it's soft and it's a quick feed. They love to chew; they have to chew because their teeth will grow through their face if they don't.

(Emily) Oh, okay. So when you're skinning your rats, pay attention to the teeth. So a lot of our rodenticides are designed in a way that favor that chewing habit. You'll notice with these specimens, some will have gnawed teeth and they're like orange in appearance, and some are more white and freshly cut. So there's a difference always with that too. There's been so much research going into like trying to understand rat behavior, to try and like one-up the rat. It's hard to keep up with because they're constantly evolving. We're finding that they're now chewing through concrete. What? -[cameraperson laughing] -How, why?

[Janelle laughing]

Because they have to gnaw their teeth down. And if they can gnaw away at the foundation of a house that's concrete, think about all the brick buildings in Chicago, that's an easy access point for them. So a lotta things we tell people when we do these services is like, "Take a walk around your foundation, look for gaps. "Make sure your doors "don't have two-inch openings underneath them "because they will, using light, odor, and airflow, detect that pathway." Yeah, it's basically a neon sign being like, "Come here. Party's in the house." -Exactly. -Oh man. So we can't be mad at the rats. The rats are just-- They're just doin' their thing. We should be mad at us because we're perpetuating their success. Come on, Rob! I thought I was gonna have all these rat friends and maybe I could be like the king of them or something. The king of rats? This is one of the snap traps, it's pretty... I mean, feel how tight that is, -you're not escapin' that. -No.

(Janelle) Unless you chew your limbs off, which is also something that they do. No!

[Janelle laughing]

Like in that with "72 hour" movie, where the guy gets his arm. Oh, "Saw"?

(Cameraperson) "127 Hours." -120... -Oh. [laughing] That is so many more hours! And he gets jammed in between a rock and a hard place, and he has to saw his own arm off. Oh my gosh. Rats do that all the time. Rats do that because they will survive.

(Describer) Emily drops the trap. Then picks it up.

-And having one less leg, -[trap tumbling] sure, it's gonna make them like the runt of the litter, but they're still gonna survive. -(Rob) Can I see that? -Yeah. -That is intense. -Ooh. A lotta times, when we finally get calls from people, we'll find all those little wooden Victor traps in there, and those things are so flimsy, they're not gonna do a darn thing for a rat. -Oh man. -This is the rat-sized one. -Oh boy. -Whoa!

(Describer) ...like a typical mousetrap.

Feel this tension. Ah! Careful. [laughing] Yikes! This is like some "Ben and Jerry"... -Not Ben and Jerry. -Ice cream? [laughing] "Tom and Jerry." [laughing] Rat ice cream. This is not like a Ben and Jerry ice cream. Yeah, this is like the "Tom and Jerry." "Tom and Jerry," yup. -Yeah, whoa. -Yeah. So how do you set this thing? I'm scared. I'm not gonna touch it. Oh whoa, okay, I'm not gonna touch it. Ooh, look at this lineup.

(Describer) She shows a phone photo of three rats crushed in the traps.

-Dang! -Ooh, wow. Oh boy.

(Janelle) A day in the life, everybody.

(speaker) I can set it for you if you want? -(Emily) Oh yeah. -Thanks for sharing, Sean.

(Describer) Rob's fan, Jesse, takes the trap.

-[laughing] -(Sean) So like-- That's what I'm here for. You can do a fast or a slow release. -Ooh. -So if you want... Yeah, so depending on which side because like--

(Rob) Why, why would you choose fast or slow?

(Sean) You know, honestly, I don't know the answer to that one.

(Janelle) I don't know.

(speaker) The right side is more sensitive.

(Janelle) Oh. So I normally put it towards the left-hand side.

(Janelle) Ah. Generally, I take a half piece of pepperoni, slide it under the little yellow trigger, mash it on there, and you get your rats. -Wow. -Oh, okay. So different things to bait them with, man, that is always an interesting topic. Yeah, I love the half a pepperoni, very specific. -Yeah. -Not the whole pepperoni. Because they'll try to grab it, and as that detects their sensitivity... See, he's got this down to a science. At different times of year, rats are after different things. So we have a supply of Slim Jims here for them to grab. At certain times of the year, they like fats, so we'll do avocado slices. I know one guy who swears by Hershey's chocolate syrup in that little cup in the trap. -Yup, that one. -(Rob) Yeah.

(speaker) You'd be very surprised how much peanut butter actually doesn't work that much.

(Describer) Jesse pokes traps with a stick.

Shall we do it?

[trap snapping]

-Whoa! -[everyone laughing] Dang! Yeah, don't get your fingers stuck in that. [laughing] Yoinks. I feel like my blood pressure, whew! It's a thrill. [laughing] Yeah, hey. "Professional." This is happening all over the city all the time. All over the country. -Yeah, all over the country. -All over the world.

(Janelle) I was in Italy in September, ugh, you would not believe the rats there. Is that just what you do when you travel-- -I know. -You're lookin' for the rats? I can't unsee rat stations, it's just a part of my life now. I didn't choose the rats, the rat chose me. We do have a rat mascot that I bring out to kids' activities, but--

[cameraperson laughing]

What do you mean, "But"? There is no but to that.

(Describer) They head downstairs.

(Janelle) It's a mess down here, like any basement in Chicago. This is Rosie the Rodent. Oh, I love it.

(Describer) A cute mascot head.

She usually comes out for Chicago Wolves hockey games because Skates, the Wolf mascot, you know, the natural prey would be a rodent. We do a little skit where we play a game of cat and mouse. I love that. -I gotta find the body. -She's so cute. Yeah, I think her body might be in this red bag. -Let me check the body bag. -She's adorable.

(Describer) She sets the head on a smaller brown head.

Hold this so she doesn't fall.

(Describer) Emily takes it.

Oh yeah, this is the big-bellied costume. Do you wanna take this upstairs?

(Emily) Please, put this on. Yeah, we had to make a butt patch for her because we had an incident, so. -Oh no. -Uh oh. Oh my gosh, it comes with feet!

(Rob) Oh my gosh, this is actually like a thing.

(Describer) They give the pieces to Jesse.

Oh my God, alright. You had no idea this was what your job was gonna be. -I had absolutely no idea. -[Emily laughing] Oh, and there's just like a plain fur body part too, but that's a little bit too creepy. The kids tend to get scared when we do it that way. -(Rob) Oh, really? -[Janelle and Emily laughing] So, what's this guy's story? -Yeah, what about this guy? -This is our bat.

(Describer) The brown head.

We do a lot of pollinator activations with museums and kids. I'm sure you've heard of "Stellaluna," the children's book, we did some theater involvement with that. And we also have a honeybee mascot, which is everybody's favorite. That's Zippy, and--

(Emily) Oh, cute.

(Janelle) He comes out more than all the others. Oh, that's fun. I mean, I think maybe a bumblebee is maybe a little cuter than a giant bat 'cause... To some, not me. Just when you think you can predict how people will react, it's just different every time. Adults too, it's a traumatic thing sometimes. I just wanna take a quick peek to see if there's any more cool equipment that I can show you while we're down here. Oh, there's this thing. What is this?

(Describer) Emily finds an older mixing machine.

(Rob) More arsenic mixing?

(Emily) Yeah, this kinda looks like you would just...

(Rob) Or that one's just for biscuits. That's just literally for biscuits.

(Describer) She turns a crank on it.

(Emily) You don't want to confuse it with the arsenic one. -Yeah. -Janelle, what's this guy?

(Janelle) Ooh, that's what I was looking for. So that's one of the oatmeal/arsenic concoction mixer machines. Oh okay, -so it is for breakfast -(Janelle) Yeah. I'm so glad that there's more regulation on it. I can't imagine the people who got sick doing this. Uh-huh. -[Emily sighing] -Talk about job risks, right? Yeah.

(Describer) Upstairs, Jesse wears the mascot body.

(Rob) Whoa, yeah! The same company that makes the Packers hats--

(cameraperson) Perfection.

(Describer) The uniform includes a cheese tie.

-Oh cool. -Nice.

(cameraperson) Did you get it at the castle? No, a special order, I know a guy.

(Describer) He wears the head.

-Sweet okay, picture? -There ya go. [laughing]

(Describer) They pose for photos.

[camera snapping photos]

(cameraperson) If you all did like a rat dance together, -ya know-- -Rat dance?

(both) What is a rat dance? Oh, you have to be like, "Oh no rats!" -Oh yeah, like. -[Janelle laughing]

(Describer) They hop like they're avoiding rats while Rosie strikes a threatening pose.

Ah! Yoinks!

(Describer) Rob points a trap at Rosie.

Oh my gosh. [laughing] -I probably shouldn't even-- -[trap snapping]

(Describer) He drops it.

-Ooh, Rob! -[everyone yelling] "Rob, Rob!"

(Rob) Sorry, I'm a workplace hazard. "Professional." This has been amazing. Yeah, thank you for coming into my world. -We have created a bond here -Yes. ...that will never be broken. -That's true. -Rats. "Rats 5 Ever."

(Emily) Stay tuned for part two, when Rob and I join our friends to explore our rats from the inside out. It's gonna be so gross!

(Emily) It still has brains on it.
