Adrian Monk: You found the hotel key card, so you knew where he was staying. You ran the whole way. You probably didn't even notice that it started to rain. [to the busboy] You. It was you. You filthy, disgusting animal. You make me sick!
Busboy: Me?
Sharona: What are you doing? He's a busboy.
Adrian Monk: Sharona, don't you recognize him from the subway? He's the urinator. Urinator! It was you. Don't, don't, don't, don't try to deny it.
Captain Stottlemeyer: Monk!
Adrian Monk: We saw what you-
Captain Stottlemeyer: Monk! Could we get back to the quadruple homicide, please?
Adrian Monk: Yeah, he followed the ambassador to the hotel, the ambassador must have noticed the jewelry, Leight killed them all, switched coats, and that's how one of them was wet. You. Where were you raised? I mean, how can you live with yourself? Disgusting pig. And you work in the food service industry, for god's sake.
Sharona: Will you control yourself?
Captain Walter Cage: The ballistics check out. The wife was killed with the same gun. Mr. Leight, you're under arrest for four counts of premeditated homicide.
Adrian Monk: Sir, captain Cage, I'm going to need to borrow these handcuffs, 'cause you're going down, Mr.
Pee.
Captain Stottlemeyer: Monk.
Sharona: Adrian, that man took a whiz in the subway. That man killed four people in cold blood. Now, who do you think we should arrest?
Adrian Monk: ... The murderer.
