Quote from Lieutenant Disher in Mr. Monk and the Lady Next Door
Lieutenant Disher: It looks like it's an inside job. Security tapes are missing, and the store gets re-supplied the first Tuesday of every month.
Captain Stottlemeyer: And that was yesterday, so he was plugged in somehow. We're putting together some names, going back ten years, everybody that's ever worked here.
Adrian Monk: You don't have to go back ten years. The manager only worked here for a year. The killer wore a ski mask, ergo, the killer was afraid he'd be recognized, ergo, the killer must have worked here recently.
Lieutenant Disher: "Ergo" the killer? What's that, Hungarian?
Captain Stottlemeyer: His name isn't "Ergo," Randy.
