A king was about to go to war,he locks his wife (the beautiful queen),in the room & gave the key to his best friend & says,If I am not back within 4 days,open the room and she is yours. He sits on his horse & hits the road. Half an hour later he notices a dust cloud & sound behind him. He stops & sees his friend riding very fast toward him.'' What's wrong ? king asks. Out of breadth,his friend answers,it is the wrong key...!''
