Quote from Adrian Monk in Mr. Monk and the Birds and the Bees
Lieutenant Disher: So he comes running downstairs. The intruder fires, misses, hits the wall. Husband returns fire. Bang. One shot. End of story. Adrian Monk: One shot. Bang. End of Story. The soles of his shoes are clean. Lieutenant Disher: So? Adrian Monk: Well, he cut through the garden out back. You think he wiped his feet? Lieutenant Disher: Well, it makes sense. He did want to leave footprints. Adrian Monk: But he did leave footprints on the patio. I saw them when I came in. Why would he wipe his feet? Lieutenant Disher: You wiped your feet. Adrian Monk: But I'm me. That doesn't count. Why would a kid - a burglar - stop and wipe his feet? That doesn't make any sense.
