Speaking of "pie-eyed", one of the more fascinating math identities relating the numerical constants is the formula:

e^[pi]*i = -1

A more well-known equation is:

pi + e = Good Eatin'

"Euler's identity" is usually expressed as:

e^(i*pi)+1 = 0

This equation has the five most important constants in analysis in one compact equation!

And if the equation is slighlty modified to include 1 and 0 that gives two more important constants of the computer age.
