“Waitress: Sorry we’re out of pie. Me: (knows math) That is literally impossible.”

“Pi” (an irrational number) shouldn’t be confused with “pie” (a food), but there are jokes.

Wikipedia: Pi
The number π (/paɪ/; spelled out as pi) is a mathematical constant, approximately equal to 3.14159, that is the ratio of a circle’s circumference to its diameter. It appears in many formulae across mathematics and physics, and some of these formulae are commonly used for defining π, to avoid relying on the definition of the length of a curve.
 
The number π is an irrational number, meaning that it cannot be expressed exactly as a ratio of two integers, although fractions such as 22/7 are commonly used to approximate it. Consequently, its decimal representation never ends, nor enters a permanently repeating pattern. It is a transcendental number, meaning that it cannot be a solution of an algebraic equation involving only finite sums, products, powers, and integers.
