''Man: An argument isn't just contradiction.
Mr. Vibrating: It can be.
Man: No it can't. An argument is a connected series of statements intended to establish a proposition.
Mr. Vibrating: No it isn't.
Man: Yes it is! It's not just contradiction.
Mr. Vibrating: Look, if I argue with you, I must take up a contrary position.
Man: Yes, but that's not just saying 'No it isn't.'
Mr. Vibrating: Yes it is!
Man: No it isn't!
Man: Argument is an intellectual process. Contradiction is just the automatic gainsaying of any statement the other person makes.
(short pause)
Mr. Vibrating: No it isn't.
Man: It is.''

Hilarious sketch!
