Dr. 'Doc' Daneeka: There's a CATCH?
Yossarian: A catch?
Dr. 'Doc' Daneeka: Sure. Catch-22. Anyone who wants to get out of combat isn't really crazy, so I can't ground him.

Dr. 'Doc' Daneeka: You got it, that's Catch-22.
Yossarian: Whoo... That's some catch, that Catch-22.
Dr. 'Doc' Daneeka: It's the best there is.
