I saw a kid sitting on the curb and I asked him, "Are you an orphan?"
He said, "Yeah, what gave me away?" "You're parents did."
Listen up, genius! The joke is funny because the kid asks what gave him away as an orphan, and the punchline is "your parents did." Get it? Orphans don't have parents, so the absence of parents is what "gave him away". Bet you still don't get it, do you? You're probably one of those fellas who still think the earth is flat. Educate yourself!
