Twin Towers Pick-Up Line

Alright, listen up, buttercup. This joke is trying to be a smooth pick-up line, but it's about as smooth as sandpaper. See, the dude is saying the person is hot, right? But then he compares his hitting on them to a plane crashing into the Twin Towers. Yeah, that 9/11. It's dark humor because it makes light of a really awful tragedy that killed many people. You wouldn't understand, your brain is smoother than a baby's bottom.
