The mathematical heresy depicted here is actually numerically sound. Dividing 22 by 7 gives approximately 3.14286, while π is approximately 3.14159. The difference is about 0.00127, making 22/7 a surprisingly good rational approximation of π. The suggestion to move Pi Day from March 14th (3/14) to July 22nd (22/7) is the kind of pedantic correction that would get you uninvited from department mixers. The cartoon character's reaction—burning the evidence—is precisely what happens when you present mathematicians with inconvenient truths that threaten their cherished traditions.
