← French Jokes # Un mathématicien n'urine pas. Il fait ∏∏.

A mathematician does not urinate. He does ππ.

The joke here is actually a play on words. In French, 'il fait ππ,' sounds like 'il fait pipi,' which translates to 'he pees.' So, the humor comes from the fact that instead of saying the mathematician is urinating ('urine' in English or 'pipi' in French), the person is using a mathematical term (ππ) to imply the action. It subtly suggests that a mathematician's way of basic human functions is different from regular people, which of course, is a humorous exaggeration.
