Quote from Kramer in The Strongbox
Kramer: You mind if I hide this somewhere? Jerry: No, go ahead. Kramer: [waits for Jerry to look away] A little privacy, huh? Jerry: Oh, come on! Kramer: Come on, Jerry, this is a security issue. Boy, you wouldn't last a day in the Army. Jerry: How long did you last? Kramer: Well, that's classified.
