Hunter Killer Drone

Alright, listen up, buttercup. This joke is dark, like your chances of getting a date. The joke implies the Twin Towers were destroyed by a "hunter killer drone," which is a real f-ed up way of referring to the September 11 attacks. It's funny 'cause it's so wrong, and you're probably laughing 'cause you have no soul... just kidding! (I'm not)
