Lieutenant Disher: Captain? The lapel pin. I just remembered where I saw it.
Captain Stottlemeyer: Where?
Lieutenant Disher: Just now at my desk.
Captain Stottlemeyer: No, I mean where- Tell me about the pin, Randy.
Lieutenant Disher: Monk. He's been wearing the same pin all week for his 25th college reunion.
Captain Stottlemeyer: I think you're right. Did the victim go to Berkeley?
Lieutenant Disher: No, she worked there. She was a nurse in the university clinic for, like, 20 years.
Captain Stottlemeyer: But she didn't graduate, so this isn't her pin.
Lieutenant Disher: The killer.
Captain Stottlemeyer: It fell off the killer. Which means the killer is at the reunion with Monk?
