Why is the number two so nervous?
Because it's always even!
Because it's always even!
"Even" means both divisible by two (a number property) and calm and composed (as in "staying even-keeled"). The twist is that being "always even" sounds like it should be reassuring, but the question asks why two is nervous — the joke sets up an expectation and then deflates it.
Deliver the punchline as if it's the answer to the question but also clearly isn't — the gap between "even" meaning calm and two being nervous is where the humor lives.
Perfect for:
Math jokes rely on the same logical structure as mathematical proofs — setup (hypothesis), expectation (theorem), punchline (QED of comedy).
