I am a huge fan. One of my favorite lines is from George, but I do not remember the episode. He and Jerry are in the coffee shop and Jerry cuts at George...George's reply, instead of totally defending himself is, 'hey hey hey, just don't tell anyone.'
God I love the way George delivers a line.
Of course there is the 'It's not you its me line...you're damn right its me!'. That is my second favorite.
