Clown Suit

Alright listen up buttercup. So basically, the joke is that doing the nasty with a toddler is already super bad. But the punchline throws in a clown suit covered in blood, which means the clown did the deed and now has to clean up. It's messed up because it combines two icky things into one big pile of ew. And you, my friend, probably think clowns are funny. I bet you have never even met a bear.
