You sunk the Titanic

Alright, listen up, genius. This joke is saying you're so fat, you're basically a huge iceberg. And not just any iceberg, but the one that took down the Titanic. A ship, by the way, that was supposedly unsinkable. But you? You're so massive, you could sink anything. Get it? Also, the Titanic disaster was caused by human error, you dumb dumb. Your momma so fat she a human error!
