Farmer's Watermelons

A farmer in the country side has a watermelon patch and upon inspection he discovers that some of the local villages kids have been helping themselves to a feast and eating all his watermelons.

The farmer thinks and plots of ways to discourage the kids from eating his precious crop. He puts up a sign that reads: "WARNING! ONE OF THESE WATERMELONS CONTAINS CYANIDE!"

He smiled smugly as he watched the kids run off the next night without eating any of his melons.

A week later the farmer returns to the watermelon patch to discover that none of the watermelons have been eaten, but finds a new sign that reads: "NOW THERE ARE TWO!"
