It's Pi Day!
Once upon a time there was an old farmer in West Virginia. His son Zeke was very bright, and was awarded multiple scholarships to attend college. He was the first person in the family to have a higher education.
Zeke majored in Algebra.
When Zeke came home for spring break, he took a trip with his dad to the general store. The usual gang of loafers were sitting around the wood stove, drinking RC Cola, chewing tobacco, and telling lies.
The farmer wanted to show off his educated son.
“Zeke, say something in that there Algy-bra,” said the father. “I always wanted to have somebody in the family who spoke a foreign language.”
Zeke was pretty flustered, and blurted out, “Pi R Square!”
“Confound it!” muttered the farmer. “What in tarnation are they teachin' you at that there college?”
“Everybody knows pie are round! Cornbread are square!”
