A prisoner is told "If you tell a lie we will hang you; if you
tell the truth we will shoot you." What can he say to save himself?
You will hang me. If they hang him, then the statement was true and
they could only hang him for telling a lie. If they shoot him, then it
makes the statement a lie and they were only to shoot him for telling
the truth. An alternate solution is to say, "You will not shoot me,"
leading to the same quandary for the killers.
A wise king devised a contest to see who would receive the
Princess' hand in marriage. The Princess was put in a 50 x 50 foot
carpeted room. Each of her four suitors were put in one corner of the
room with a small box to stand on. The first one to touch the Princess'
hand would be the winner and become the new King.
The rules were the contestants could not walk over the carpet, cross the plane of the carpet, or hang from anything; nor could they use anything but their body and wits (i.e. no magic, telepathy, nor any items such as ladders, block and tackles etc). One suitor figured out a way and married the Princess and became the new King. What did he do?
Asked the princess to touch his hand.

Two guards were on duty outside a barracks. One faced up the road
to watch for anyone approaching from the North. The other looked down the
road to see if anyone approached from the South. Suddenly one of them
said to the other, "Why are you smiling?"
How did he know his companion was smiling?
They were facing each other. As to why his companion was smiling, the
world may never know.
