This weeks winner is phillieg. CONGRATS!!!!!!!!!!!!!!!!!!!!!!!!!

RIDDLE: You are standing in front of a room with one lightbulb inside of it. You cannot see if it is on or off. Outside the room there are 3 switches in the off positions. You may turn the switches any way you want to. You stop turning the switches, enter the room and know which switch controls the lightbulb. How?

ANSWER: You turn 2 switches "on" and leave 1 switch "off" and wait about a minute. Then enter the room, but just before you enter, turn one switch from "on" to "off". Once in the room, feel the lightbulb, if it is warm, but off, it has to be the last switch you turned off. If it si on, it has to be the switch left on. If it is cold is off, it has to be the switch you left in the off position.
