Quote from Monica in The One with All the Rugby
Joey: What's up? Monica: This switch thing has been driving me crazy. So I turned it off and checked every outlet. Now, four of them don't work, which means one has to be controlled by the switch. So I plugged things in all four outlets that make noise. That way, when I turn it on, I just follow the noise and find out which one it is. Joey: Bet I stopped listening before you did. Rachel: You know, you also could have used lamps and followed the light. Monica: Yeah, well, I'm using noise.
