You think you're pretty clever, eh? I'll fix you. :P
And you other smartypants types, no giving away the answer utill 'Aloverssunset' posts ... I mean it. Grr.
Here's the puzzle:
You are lost in a labyrinth. You finally come to what you know to be the exit: two doors, one of which opens to eternal freedom - the other, to instant death.
Each of the doors is guarded by a robot. One always lies, and one always tells the truth.
Both the doors and the robots look exactly alike. Of course, you have no idea which robot guards which door, or which of the doors or robots are which either.
Thankfully, you can avoid taking a 50/50 gamble on the doors by asking one robot a single question.
What is the question?
