Mr. Monk and the Class Reunion - S5-E6
Randy Disher: Captain? I, uh, tracked down Kalimarakis. I don't think he's our guy. Number one, it turns out he was allowed to join the Olympic swim team as an alternate. He got a waiver.
Captain Stottlemeyer: So there's no motive.
Disher: Right. Number two, he's dead. He died in 1995. And number three, he moved to Europe in the late 80's. So there's no record of him ever returning.
Stottlemeyer: Randy. Randy. Excuse me. Sorry to interrupt you, but could you read number two again?
Disher: Okeedoke. He's dead.
Stottlemeyer: Right. See, I probably would have stopped reading after number two. In fact, I would have read number two first.
Disher: You would have switched them?
Stottlemeyer: Yeah. But that's just me. And probably every other adult on the planet Earth.
Answer: Notice also that in the opening credits scene when he is touching parking meters her also wipes his hand on his clothes each time he does it.
