Via Sarah at Just Another False Alarm, this useful site, Colin's movie monologue page. Here's Michael Dorsey (Dustin Hoffman) arguing with his agent George Fields (Sydney Pollack) in Tootsie:
George: They can't all be idiots, Michael - you argue with everybody! You've got one of the worst reputations in this town, Michael! Nobody will hire you.
Michael: (slowly, as he processes this) Are you saying that nobody in New York will work with me?
George: Oh no, that's too limited. Nobody in Hollywood wants to work with you, either. I can't even send you up for a commercial - you played a tomato for thirty seconds, they went a half a day over schedule 'cause you wouldn't sit down.
Michael: Yes. It wasn't logical.
George: You were a tomato! A tomato doesn't have logic! A tomato can't move!
Michael: (worked up) That's what I said, so if he can't move, how's he gonna sit down, George? I was a stand-up tomato, a juicy, sexy beefsteak tomato! Nobody does vegetables like me! I did an evening of vegetables Off-Broadway! I did the best tomato, the best cucumber - I did an endive salad that knocked the critics on their ass!
George: (at the end of his rope) Michael, I-I'm trying to stay calm here. You, uh - are a wonderful actor.
Michael: (sulking): Thank you.
George: But you're too much trouble. Get some therapy.
