Quote from Adrian Monk in Mr. Monk and the Red-Headed Stranger
Captain Stottlemeyer: Monk, look. My heroes have always been cowboys too. It's either "A," the blind woman, who has zero motive, or it's "B," your buddy, the Red-headed Stranger. Lieutenant Disher: Who had motive, means and opportunity and was identified by the only witness at the scene. Captain Stottlemeyer: "A" or "B," Monk? Adrian Monk: I think it's "C." Captain Stottlemeyer: "C"? What the hell is "C"? Adrian Monk: I don't know yet.
