College Grad
A Hillbilly family's only son had saved up money to go to college and after about 3 years he came back home. They were sitting around the dinner table when the dad said:
-''Well son, you done gone to college so you must be perty smart. Why don't you speak some math fer' us?''
-''Ok, Pa'', the son said then, ''Pi R squared.''
After a moment the Dad said:
-''Why son, they ain't teached ya nothin'! Pie are round, cornbread are square.''
