Pi Day Jokes And Puns To Tell On March 14

Punny Pi Day jokes everyone will chuckle at

Like my favorite middle-school teacher always said: The problem with math jokes and puns is that calculus jokes are derivative, trig jokes are too graphic, algebra jokes are formulaic and arithmetic jokes are just basic. (But I guess the occasional statistics joke is an outlier.)

If you are cringing right now, you know how my entire eighth-grade math class felt every day. However, it is important to know a few good jokes for every occasion—including Pi Day jokes to celebrate Pi Day on March 14—even if only the smarty-pants in the room will get them. Sure, there are really interesting pi facts out there, but these jokes prove that math can be funny too.

So if you’re looking for ways to celebrate Pi Day, indulge in these hilarious Pi Day jokes. Don’t worry: Unlike pi, they won’t go on forever.
