You are locked in a room with two people and two doors. Remain in the room and you will die of thirst. One of the people will always lie and the other will always tell the truth.

get the answers......google is a wonderful thing...

There was no Google in 1969

I had "google" eyes for Raquel Welch, back then.. LOL!
