Post:

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.

Comment:

If this were an interview question, the correct response would be "Do you have any relevant questions for me? Because have a long list of things that more deserving of my precious time than to think about this!

That's not the answer. It's an answer. The question isn't very contained so there are a lot of answers. You can get someone else to switch the switches in order while you watch. Or you can install a camera in the room and then pull the switches. You can keep the door open to see which switches works, etc. Probably a million more solutions.
