Here's a fun brain teaser for you guys.?

well, what you do is you turn on one of the switches allowing enough time for the bulb to get hot! then, you turn the switch off!!!! after this, you turn the second switch on and leave it on!! you leave the third switch off!!! at this point, you will go up to the third floor and if the bulb is on, it is the second switch that controls it. if the bulb is off but warm, it is the 1st switch that controls it. if the bulb is off and cold, it is the 3rd switch that controls it!!!!!!!!!! i win!!!!! =]
