Do you like In-N-Out?

Alright listen up, nimrod. This joke is funny because it uses a double entendre. "In-N-Out" is a popular fast food chain, but it also sounds like "in and out of" which implies something sexual. Get it, dumbo? Bet you didn't! By the way, I can tell you need glasses by the way you look, you probably can't see 10 feet in front of you.
