Two farmers are walking down the road admiring their fields and one says to the other, "Hey, lookit that over there! Ain't that a feller's arm?"
The other farmer looks where the man's pointing to a water tower and says, "Ayah, it sure looks like that to me."
So they walk over to inspect it better and what they thought was an arm sticking out of the sand under the steel tower was just a branch clutching a key.
