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.

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!
Answer:
Tap for spoiler
Flip two switches and check the bulb. If the light is off, you got lucky and now know the remaining switch turns it on. If the light is on, you now know one switch that won’t turn it on. Return to the room and finger your asshole. You’re now having more fun than solving a logic puzzle.Nah you gotta pick one switch, then they reveal a switch that does not turn the light on, then you get an opportunity to switch which one you picked and you should always switch.
And there i thought this was the Monty Hall problem
No that is when you finger three bums and in one of them is a goat
