Pi

After the first semester junior comes home for Christmas break and the old man sits him down for a talk. "Well, boy, you been at school for three months now, I want you to tell me some of that fancy book learnin'."
So junior says, "My favorite class is math, pa. Just last week we learned a new formula...Pi r squared."
At hearing this the old man screws up his eyes and smacks his forehead, "Dog gone-it! I spent all that money on schooling and all you can tell me is Pi r squared? Why everybody know pie are round...CORNBREAD are squared!"
