Back in college, a local pizza joint was named πr2, pronounced Pies Are Squared. They served square pizza slices. Which kind of defeated the original point of the πr2 formula...
They cheated a bit. I seem to recall they had a sign in one place that said πr2, and another sign elsewhere that said "Pies Are Squared". Or maybe the π had a very small 's tacked on. I don't remember exactly how the name was communicated.
