Ed, The comment about the cryptic title of my rant was tongue in check, I hope. Just in case it wasn't tho', and you are genuwinely so slow it takes you 20 minutes to catch a joke here's the explanation:

In a joke so old it makes me look plum' spring chickenish, a country boy comes home for the first time after being away at college. His father, wanting to make sure his tuition dollars are being wisely used, insists that Junior say something smart, so Junior pops off with the first thing that comes to mind: "Pi r square," where upon Pop begins whupping up on Junior with his hat as he yells, "No, no, no, you ignoramus! Everybody knows pie are round. *Cornbread* are square!"

The first time I ever heard that one was one morning at least half a century, as told by the one and only Cookie Harris.

And deponent sayeth not further.
