So it looks like Half Life 2 isn't gonna be out for a long time and we arent allowed to discuss 'teh beta' so heres a riddle.
Mods, ban me if you wish, but I'm just trying to liven up a very boring forum.
Okay, so, this was taken from David 'dopey' Blaine, who at the moment is nearing the end of his inprisonment in a glass box and if you've already heard it please dont answer and let someone else have a go!
The Riddle
Theres a house.
The house contains three floors.
On the top floor is a light bulb.
The Middle floor is empty.
The bottom floor contains three switches, one of which operates the light on the third floor.
All three floors are linked by a flight of stairs.
Question - How many switches does one need to 'test' to find the switch that operates the light on the third floor? Switches can be left on or off as you please. And the lightbulb can only be checked once.
Please give your answer and your reason why. If for some reason no-one gets it I'll post the answer later on.
