Watermelons

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 up with 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 ran off, made up their own sign 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!"
