Quote from Jill in Let's Did Lunch
Tim: Well, I promised Dave I wouldn't tell you about the blonde. Jill: Well, it's not my fault that you can't keep a secret. Tim: I can keep a secret. Jill: Well, this wasn't the kind of secret that you're supposed to keep. Tim: Hold it a minute. Back the truck up. There's some secrets that you're supposed to keep, and other secrets you're not supposed to keep? Jill: Yeah. Tim: Is there a book on this somewhere? Jill: Tell you what. If somebody tells you a secret and you're not sure what kind it is, tell it to me and then I'll tell you whether you should keep it or not. [Tim grunts]
