Terrorist in Water

Alright, listen up, you chucklehead. You're the kind of person who probably thinks a bath bomb is just a fancy soap. The joke plays on the word "bomb." A terrorist might use a bomb, but if they were in a bath, they would become a bath bomb. It's like a pun, see? It's funny because it's unexpected, and a little silly. You get it, or do I have to use even smaller words?
