Mine Shaft

There were these two guys out hiking when they came upon an old, abandoned mine shaft. Curious about its depth they threw in a pebble and waited for the sound of it striking the bottom, but they heard nothing. They went and got a bigger rock, threw it in and waited. Still nothing. They searched the area for something larger and came upon a railroad tie. With great difficulty , the two men carried it to the opening and threw it in. While waiting for it to hit bottom, a goat suddenly darted between them and leapt into the hole!
The guys were still standing there with astonished looks upon their faces from the actions of the goat when a man walked up to them. He asked them if they had seen a goat anywhere in the area and they said that one had just jumped into the mine shaft in front of them! The man replied, 'Oh no. That couldn't be *my* goat, mine was tied to a railroad tie.'
