There was a farmer who grew watermelons. He was doing pretty well, but he was disturbed by some local kids who would sneak into his watermelon patch at night and eat his watermelons. After some careful thought, he came upwith a clever idea that he thought would scare the kids away for sure. He made up a sign and posted it in the field.

The next day, the kids show up and they saw the sign which read: "Warning! One of the watermelons in this field has been injected with cyanide."

The kids run off, made up their ownsign and posted it next to the farmer`s sign. When the farmer returned, he surveyed the field. He noticed that no watermelons are missing, but the sign next to his read:

"Now there are two!!!"
