Six-y Predator

Alright, listen up, buttercup. This joke is about child predators, which are nasty humans who like kids way too much, and it uses a pun. See, instead of saying someone is "sexy", they say "six-y" because the kid is six years old. It's dark humor because it's about a really sick topic, and you're probably laughing because you have the emotional intelligence of a toaster.
