Alright listen up, chucklehead. This "joke" is alluding to the fact that Bill Cosby has a fantasy of tickling kids, which is a euphemism for sexual abuse. But the punchline is that instead of him preying on children, he's going to be the one getting "tickled" by his cellmates in prison. I know you are not smart but try to follow, ok?
