Osama's Airport Alternative

Alright, listen up, buttercup. This "joke" is about the 9/11 attacks. Osama bin Laden was the head honcho of al-Qaeda, the group that masterminded the whole shebang. The "runway is full" line is a dark way of saying he decided to use the Twin Towers as targets because the airports were too risky, or something. And you? You're about as sharp as a marble, aren't ya?
