Alright, listen up, smarty pants. So, the Titanic is, like, sinking, right? Total disaster. Everyone's screaming. But this one dude is all, "Hold up, I'm using the sink!" It's funny because it's so not the right time to worry about washing your hands. You probably think that washing hands is important, but not when you are about to drown! The joke is funny because it is unexpected and absurd.
