What do an engineer at NASA and Ree Drummond have in common? Pi! Although NASA uses pi to measure planets while The Pioneer Woman uses pies as an excuse to eat ice cream (pi a la mode anyone?), everyone can agree on the importance of pi—whether of the math or lattice crust variety!

Speaking of pi, as March rolls around each year, math enthusiasts and pastry lovers alike rejoice in the celebration of Pi Day! This unique spring holiday, dedicated to the mathematical constant pi, is a perfect time to embrace the joy of the never-ending number with some silly Pi Day jokes. But before we get into the fun part of the holiday, what’s 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!
