Scott,

I think you probably missed the thread that may have precipitated this one. (I'm still not sure that it wasn't a Joke) [Linked Image]

Anyway, OK guys, Here's your test: (if you've heard this before please hold out the answer a bit so we can get some good guesses in).

There's a Light fixture in the Attic and a switch in the Basement (one of three) They are not in sight of each other. How would you, by yourself determine which of 3 swithches in the Basement is for the light (test equip not needed) and only go up to the Attic once to confirm?
