A Chemistry Cat post.
A cat in glasses and a bow tie, posing next to lab glassware, as if about to give a lecture. It's the advice animal of science puns. The top line sets up a pun. The bottom line lands it, with element symbols, bonds and formulas doing the heavy lifting. "I would make a chemistry joke" / "But I know I wouldn't get a reaction." "If you're not part of the solution" / "You're part of the precipitate." "I'm reading a book about helium" / "I can't put it down." Puns about sodium ("Na") and argon also get a lot of use. The cat looks slightly smug, which is the correct face for a pun. Everyone in the room groans. The cat has already moved on to the next one. Science teachers have been printing this on worksheets for years. **Why it caught on:** puns are better with a smug cat in a bow tie.
