There was a farmer
who raised 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 watermelons. After
some careful thought he came up with a clever idea that
he thought would scare the kids away for sure.
So he made up the
sign and posted it in the field. The next day the kids
show up and they see this sign, it says, "Warning, one
of the watermelons in this field has been injected with
cyanide."
So the kids run off,
make up their own sign and post it next to the sign that
the farmer made. The farmer shows up the next week and
when he looks over the field he notices that no
watermelons are missing but he notices a new sign next
to his. He drives up to the sign which read:
"Now there are two."
