Unwanted Inmates

Alright, listen up, you big dummy! This joke is playing with the word "wanted," see? When the police want someone, they're "wanted" for a crime. But "wanted" also means desired or cared for. So, the joke says orphans can't go to jail because they're not *wanted* by anyone, implying they're unloved, and therefore not "wanted" by the cops either. Get it? You probably need a snack, you're looking a little confused.
