Before the King went to war, he locked his wife (the beautiful Queen ), in the room & gave the key to his best friend & said:
"If I am not back within 4 days, open the room and she is yours"....
He sat on his horse & hit the road.
Half an hour later, the king noticed a dust cloud & sound behind him.
He stopped & saw his friend riding very fast towards him.
"What's wrong ?" the King asked.
Out of breath, his friend answered,
"It's the wrong Key...!! "
Now..
How does he know that it's the wrong key?
Please beware of the one whom you call your best friend.......
