Watermelons

A farmer in the country has a watermelon patch and upon inspection he discovers that some of the local kids have been helping themselves to a feast. The farmer thinks of ways to discourage this profit-eating situation. So 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. The farmer returns to the watermelon patch a week later to discover that none of the watermelons have been eaten, but finds another sign that reads: "NOW THERE ARE TWO!"

Idiot Chicken Farmer

An idiot decided to start a chicken farm so he bought a hundred chickens to begin with. A month later he returned to the dealer for another hundred chickens because all of the first lot had died. A month later he was back at the dealer for another hundred chickens for the second lot had also died. "But I think I know where I'm going wrong," said the idiot, "I think I'm planting them too deep."
