Any discussion of Pi, aside from its esoteric side, always brings a smile to my face. As best I can remember, it was on Beverly Hillbillies where I first heard:
"Pi R square" ..."no, it's not"... "It certainly IS" ..."No, any fool knows: CORNBREAD are square, Pie are ROUND!"
Maybe it's even older than that... anybody know fer shure? Charles Husbands
