Quote from Adrian Monk in Mr. Monk Stays in Bed
Adrian Monk: Could you turn this? Thank you. Well, that's good. Captain Stottlemeyer: What is this thing? Adrian Monk: It's a humidifier. Captain Stottlemeyer: What's that one? Adrian Monk: It's a dehumidifier. Captain Stottlemeyer: Well, don't they cancel each other out? Adrian Monk: Exactly.
