Captain Stottlemeyer: Monk, make a wish.
Adrian Monk: Okay. You loosened your belt.
Uniform Officer: I'm making room for the cake.
Adrian Monk: [to Pressman] You loosened your belt.
Kurt Pressman: Excuse me?
Adrian Monk: Your tool belt. It didn't fit, and I saw you loosen it. You didn't even know what tool to use. It wasn't your belt. Was it? I know what happened. I know the whole story. The janitor, Bradley Foster, the engineer from MIT. He was the real inventor. He took the idea to Richard Meckler, which made sense. Meckler was a patent lawyer in that same building. Self-cleaning vacuum. The fourth greatest invention since the dawn of man. Meckler knew it would be worth a fortune. You and Meckler were old pals. You were in it together. He killed Foster in the trash compactor, and you were the beard. You were the phony inventor. Meckler was greedy, but you were greedier. You decided you didn't need a partner so you killed him. You poisoned him at that reception.
Kurt Pressman: I poisoned Richard Meckler? How? You were there. So were you.
Adrian Monk: You brought him his drink. It must have been in the drink.
Kurt Pressman: I drank from it, remember? From the same glass.
Adrian Monk: The ice cubes. The ice cubes. Mine are square. These are round. So are yours. It must have been in the ice cubes.
Captain Stottlemeyer: I'll take that.
Adrian Monk: That's how you could drink from the same glass. The ice hadn't melted yet.
Captain Stottlemeyer: Randy, cuff him.
Cowboy Hank: Don't need handcuffs. There you go, son, take him away.
Adrian Monk: Cowboy Hank!
Natalie: He was available. Can you believe it?
Cowboy Hank: Sorry I'm late, buckaroos. Who's the birthday boy?
Adrian Monk: I am.
Cowboy Hank: Well, ride on my saddle, happy birthday, son.
