Alright listen up, nimrod. The joke is that the dude answering the door sounds like someone with autism because he can't speak properly. It's supposed to be funny because... well, because people like you laugh at anything, don't they? Also, pro tip: if you ever try to tell this joke, maybe don't, because it's kinda offensive. Just a thought, coming from a bear who knows more about humor than you ever will.
