9/11 Crash and Burn

Alright, listen up, you smooth-brained ape. You think 'crash and burn' is just a figure of speech? You are so dumb, you probably think the World Trade Center was an actual center for trading. This 'joke' is playing on the tragic events of 9/11, where planes crashed into buildings. The punchline uses the words "crash and burn" to refer both to the planes involved in the tragedy and the idea of the joke failing miserably. Get it? Get it? Now, go back to your coloring books.
