George Costanza (played by Jason Alexander)” "You're giving me the 'It's not you, it's me' routine? I invented 'It's not you, it's me.' Nobody tells me it's them, not me. If it's anybody, it's me!"
Gwen: "Alright, George, it's you."
George: "You're damn right it's me."
Gwen: "Look, I was just trying to...."
George: "I know what you were trying to do. Nobody does it better than me."
Gwen: "Well, I'm sure you do it very well."
George: "Yes, well, unfortunately you'll never get the chance to find out." --George and Gwen, breaking up, in Seinfeld, "The Lip Reader" episode, 506, Season 5, Episode 6, teleplay by Carol Leifer, directed by Tom Cherones, original air date October 28, 1993
