Every developer knows the old excuse: it works on my machine. This is the update for the prompt era, because now the machine isn't even the problem, the wording is.

You ran it once. It worked. You changed nothing, asked the exact same thing twice, and got a completely different answer with total confidence both times. That's not a bug, that's just what happens when the "logic" lives in a sentence instead of a function.

Printed in black on glossy white ceramic, on both sides, so whoever's holding it gets the joke without having to turn the mug round.
