Quote from Kramer in The Wallet
Helen Seinfeld: What happened to you? Kramer: Oh, well, some guy kicked me in the side of the head. Helen Seinfeld: What guy? Kramer: Crazy Joe Davola. Helen Seinfeld: Why? Kramer: Well, I was having this party and I didn't invite him and Jerry tipped him off. Jerry: Why did you tell this crazy guy that Kramer didn't invite him to his party? Jerry: I didn't know he wasn't invited.
