Here Comes the Airplane

Listen up, buttercup. This joke is about how parents often make airplane noises when they feed a kid. The punchline adds a second airplane, which references the two planes that crashed into the Twin Towers on 9/11. The joke is built on a nasty stereotype, suggesting that someone of Arab descent would make light of a terrorist attack, which is pretty messed up. You probably already knew that, though, right?
