Still Cousins

Alright, listen up, nimrod. This "joke" is about incest, which is obviously wrong and illegal. The punchline is that even if they "feel wrong," they are "still cousins," implying they're engaging in incestuous behavior. It's supposed to be funny because it's so taboo and messed up. Considering you thought this was funny, I would not be surprised if your family tree is a circle.
