On February 20, 2005 Seth Green and Matthew Senreich unleashed a horrifying monster into the world. It was half chicken, half cyborg and came with a mission to make you question and cringe at everything you once held dear about your childhood. That monstrosity was Robot Chicken, Adult Swim’s black-as-night stop motion sketch show.

Filled with blood, cursing, and sex, each minute of Robot Chicken seems designed to scar its viewers for life. Have you ever wanted to imagine your dad having sex as Inuyasha? Or what about Andy from Toy Story using Buzz Lightyear as a bong? No? It doesn’t matter. Robot Chicken has already cursed the world with both of those things and so many more horrors.

For 10 seasons, 190 episodes, and 11 specials the Adult Swim original has disturbed us as much as its silliness has made us giggle. It even won an Annie Award and six Emmys in the process. And now it’s hitting the big one-five. To celebrate Robot Chicken’s 15 years of irreverent animation, here are the 15 best sketches from this 2000s classic. Here’s to a decade and a half more of claymation madness.

15 "Law and Order: KFC" There are countless irreverent, borderline offensive Robot Chicken sketches out there, but this one is just silly. A group of chickens cluck their way through a typical episode of Law and Order. And you better believe there are a lot of DUN-DUNs in the mix.

14 "Barbie Fight Club" Ken, sick of his partner’s limitless jobs and dream house, snaps and finds solace the only way he knows how: through a Fight Club with a bunch of identically unhappy Kens. Any version of Barbie and Ken’s relationship that’s way too serious is poised to be funny. But this one and the Gone Girl parody “Gone Barbie” take the cake.

13 "The Arkham Redemption" No show is better at bonkers pop culture mashups than Robot Chicken and this is one of the best. The Joker gets locked up in Shawshank prison and has to morosely find his way out. Things only get sillier by the minute.

12 "Death Star Yo Mama" Seth Green and Matthew Senreich have always been notably great at Star Wars parodies. In this one Luke faces off against the Emperor not in a lightsaber duel or by utilizing The Force but by dissing his mama. If gems like “Your mama is so stupid she spent all day saying ‘Am not’ to R2” make you giggle, give it a watch.

11 "33 Year Old Virgin" Oh Jesus, what are we going to do with you? Robot Chicken always loves to get a sacrilegious with this fixture of Christianity. But replacing replacing Steve Carrell’s character in 40-Year-Old Virgin with the son of God is on another ridiculous level.

10 "Friday the 13th" It’s the day before Friday the 13th and Jason Voorhees simply cannot wait. Equally childlike and deeply gruesome, this short sketch embodies the two extremes this series knows all too well.

9 "Spider-Man and His Amazing Spider Senses" Well before Marvel was dominating the box office, Robot Chicken was ruthlessly mocking everyone’s favorite arachnid-themed superhero. This time Peter Parker’s hair trigger spider sense keeps going off though nothing seems to be wrong. From rogue puddles to spoiled milk, this sketch turns one of the coolest superpowers around into an everyday nightmare.

8 "This Will Only Hurt for a Second" A doctor warns a little boy not to flinch while he’s getting a shot. And his reasoning why is about as deeply graphic as this show gets. Filled with claymation blood, this sketch isn’t based on any particular show or movie, but it’s still darkly funny.

7 "The Book of Your Life" Few sketches capture just how truly and relentlessly dumb people are better than this one. After living a good life, a man makes it to heaven and God presents him with his reward: a book that will answer any question he has. But instead of learning about how many people he made smile or how his loved ones are doing back on Earth, our Average Joe only cares about how much he pooped.

6 "Take Your Daughter to Work Day" Another Star Wars classic, it’s take your daughter to work day on the Death Star. Naturally that leads to an exhausted Stormtrooper ducking and dodging through Rebel shots to save his daughter’s teddy bear. As insane as this sketch is, it’s oddly sweet for this warped show.

5 "Delicious Gummy Bears" This horrifying walk through the meadow is just one of those things you have to watch to appreciate. Make sure your sound is on low.

4 "Lil Hitler" How do you make the most despicable man to have ever existed the center of a comedy sketch? By turning him into a spoiled, elementary-aged brat. “Lil Hitler” irreverently condenses the horrors of World War II into a classroom spat in a sketch that’s the definition of black comedy.

3 "Quicksand" It’s hard to decide what’s better about this sketch, its presentation of the five stages of grief or its depressing ending. A giraffe gets stuck in quicksand and we get to watch him cycle through denial, anger, bargaining, depression and acceptance in a record amount of time.

2 "Voltron Got Served!" This one is right up there with the Star Wars “yo mama” fight, yet it’s somehow better. Voltron has to face off against an intergalactic alien who will only fight in one way: through dance. Just remember that when you run out of dance moves, you always have a super-powered sword as backup.
