An Old Watermelon Joke

Was a watermelon farmer from Kennett, MO, whose crop got ripe and every day he found a big fat juicy melon missing from his garden. He put up a sign that said "Warning: One of the Watermelons in This Patch is Poisoned!" and figured that would fix the thief. Farmer the next day came out and found his sign had been scribbled on and changed to say, "Two of the Watermelons in This Patch Are Poisoned!"
