Quote from Sharona in Mr. Monk and the Paperboy
Sharona: $400? After I saved his life? Adrian Monk: You? I pulled the train switch. Sharona: After I loosened it. Adrian Monk: You didn't loosen it. Sharona: It gave a little just before you grabbed it. Adrian Monk: Why do you say that? Why do you torture me? Sharona: Because I can.
