No Google: In one room, three light bulbs. In another, three switches. You can go into the room one time to determine which switch controls which bulb. But you must identify all three correctly.
Tell me how you do this.

Where's the Mensanet folks? This is dumb as a bucket of hair.... I didn't even get it.

In the switch room, turn switch 1 = ON, 2 = ON, 3 = leave OFF. After a minute 1 = ON, 2 = OFF, 3 = OFF. Go to the bulbs, whichever bulb is ON is controlled by switch 1. Whichever feels warm to the touch is switch 2. Cold bulb = 3.

Just googled and I am right, had to assume they were incandescent. At first was thinking about shattering the glass and watching which filament burns out, but was more complicated.
