A pair of tourists were out in the fields when they discovered an abandoned well near an old farm house. Of course theyre curious so they drop a small stone into the well, but they never hear it hit bottom. They search and find a larger rock and drop it into the well but once again hear nothing. They decide they need something larger and search the farm yard for a larger object. After much struggle, they manage to drag a large railroad tie to the edge of the well and drop it over the edge.After several seconds, a goat tears across the yard and without any hesitation, dives head first into the open hole. The two tourists stand in amazement. About then a farmer appears and tells them he is looking for a lost goat. The tourists tell the farmer about the goat diving into the well.That couldnt be my goat, the farmer replies, My goat was grazing in the field roped to a railroa d tie!
