Quote from Julie Teeger in Mr. Monk and the Red Herring
Adrian Monk: Is there money in the house? Natalie: No. Adrian Monk: What about the coffee can? Isn't that where you hide your money? Natalie: How did you know that? Adrian Monk: There's coffee grounds on the counter indicating that it's been opened recently, but you don't have a coffeemaker. Julie Teeger: Wow, he's like Velma from Scooby-Doo.
