Life. It Really Does All Come Down to Costanza.

Even, it turns out, in Victorian England, as per Elizabeth Gaskell's North and South:

"Oh Mr. Thornton, I am not good enough!"

"Not good enough!  Don't mock my own deep feeling of unworthiness."

JERRY:You have no idea what an idiot it. Elaine just gave me a chance to get out and I didn't take it. (Points to himself) This is an idiot.

GEORGE: Is that right? (Showing him up) I just threw away a lifetime of guilt-free sex and floor seats for ever sporting event in Madison Square Garden. So please a little respect. For I am Costanza. Lord of the Idiots!
