A man is found hanging in a room 30 feet off the ground. There is nothing else in the room except for a large puddle of water on the ground. The police can't see any way the man could have climbed the walls to get to where he is hanging.
How did this man hang himself?
He stood on a tall block of ice and put the noose around his neck. Once the ice melted, he was hung, and all that was left was a puddle of water on the ground.
A king has no sons, no daughters, and no queen. For this reason he must decide who will take the throne after he dies. To do this he decides that he will give all of the children of the kingdom a single seed. Whichever child has the largest, most beautiful plant will earn the throne; this being a metaphor for the kingdom.
At the end of the contest all of the children came to the palace with their enormous and beautiful plants in hand. After he looks at all of the children's pots, he finally decides that the little girl with an empty pot will be the next Queen. Why did he choose this little girl over all of the other children with their beautiful plants?
The king gave them all fake seeds and the little girl was the only honest child who didn't switch seeds.
