If you're anything like Ree Drummond, you're no stranger to pie. Pi, on the other hand, can be a bit of a head-scratcher. But whether or not you've memorized its digits, you can still partake in all the fun of Pi Day! The unique March holiday celebrating the mathematical constant "pi" is the prime time to put away a slice of pie—and tell some witty Pi Day jokes! But before you put your Pi Day pants on, take a second to get the scoop (or slice) on pi.

To refresh your memory, pi is the mathematical constant representing the ratio of a circle's circumference to its diameter. Like your reasoning for eating that extra slice of pie after dinner, the number pi is irrational, approximately equal to 3.14159 (and so on, infinitely). Because the rounded number of pi is 3.14, Pi Day falls on March 14 (3/14).

Although Pi Day itself is finite, the laughter that comes from sharing pi-related jokes will stretch into infinity, just like the digits of pi! Whether you’re celebrating the mathematical holiday by throwing a pizza party, eating a slice of your favorite pie, or solving some math equations, anyone can benefit from a few Pi Day jokes to lighten the mood. Join us as we explore some of the most preposterous Pi Day jokes, pi puns, and math one-liners that are sure to tickle your funny bone and perhaps even inspire you to bake a pie or two!
