Question: (riddle) This is the riddle of the two guys guarding the two doors.  Great riddle, check details.? In this riddle, you are trying to get to some location.  The only way to go is to go through one of the 2 doors, guarded by 2 guys (1 guy 4 1 door.). One of them will always lie and the other will always tell the truth.  You need to figure out which door to use to get to the location.  Please post a comment if you need more info.\nP.S. you will hate me because this will be in your mind forever.

Answer: Say to the first guy.."if I asked the other guy which door to choose, what would he tell me?"\n\nThen choose the "other door".\n\nIf you asked the truthful one, he will tell you that the lyer would sugest the wrong door.\n\nAnd if you asked the lyer, he would know which door the truthful would say, but, being a lyer he will give you the wrong answer.\n\nEither way, if you pick the other door you win!
