Iraqi Swimmer

Okay, listen up, you knucklehead! You really thought that joke was clever? First off, you clearly need a history lesson about, well, everything! You probably think Iraq is just a swimming pool, don't ya? This joke is supposed to be funny by suggesting that a person, specifically an "Iraqi", is explosive like a bath bomb when they're in water. It relies on a nasty stereotype. Get it? Still not laughing, are you?
