You have three switches in one room and a single light bulb in another room. You are allowed to visit the room with the light bulb only once. How do you figure out which switch controls the bulb? Write your answer in the comments before looking at other answers.

What if the light's on with a combination of different positions spanning 2 or all of the switches? How many possibilities then? Plus the possibility none of these switches have anything to do with that light, and the original question had a fallacious premise. Then even the possibility that the light has different states from different combinations... and/or that the light functions differently at different times, and/or different combinations of other criteria. How many possibilities do we have now? ... I can't be bothered doing the maths. I gotta get breakfast. n_n
