Quote from Adrian Monk in Mr. Monk Goes to the Bank
Natalie: Mr. Monk, look, look, look! A toaster! It's in perfect condition!
Adrian Monk: No. No, thank you.
Natalie: Look, it's five dollars. Please, I'll pay for it.
Adrian Monk: Natalie, it's used. I'm not gonna make food in somebody else's toaster. Unless I'm wrong, that's how the bubonic plague got started.
Natalie: That's not true.
Adrian Monk: I said, unless I'm wrong.
