Quote from Sharona in Mr. Monk and the Marathon Man
Sharona: Why don't you sit down? [Monk shakes his head] Well, at least hold the pole. [Monk shakes his head] How do you explain this: I touch everything you're afraid to touch, and I never get sick. Adrian Monk: I can't explain it. It's inexplicable. Sharona: No. You're inexplicable.
