There are a few trees in a garden. On one of them, a pear tree, there are pears (quite logical). But after a strong wind blew, there were neither pears on the tree nor on the ground. How come?
ANSWER: At first, there were 2 pears on the tree. After the wind blew, one pear fell on the ground. So there where no pears on the tree and there were no pears on the ground.
