9/11 Joke

Listen up, buttercup. This joke is dark. See, the comedian is making a joke about 9/11. It is dark because 9/11 was a real tragedy where planes crashed into buildings and a whole lot of people went bye-bye. The punchline is that the jokes about 9/11 "crash and burn", much like the planes did. I know, I know, you probably think a 'punchline' is just what happens when you get hit. Sad.
