Two guys are hiking through the woods... And they come into a clearing with a huge hole in the middle. The hole is very deep, the men can't see the bottom, it's just black. So one of the guys picks up a few rocks and tosses them in. They both wait to hear the rocks hit the bottom, but they never do. So the second guy picks up a pretty big rock, and heaves it into the hole. Again, they listen but never hear the rock hit the bottom. They're both amazed at how deep this hole must be. So the first guy sees a railroad tie at the edge of the woods. They both grab an end and lug it over to the hole, and toss it in. They're waiting to hear it hit, when out of nowhere a goat comes bounding out of the woods, ears pinned back, just running as fat as it can. The goat jumps into the hole. They're both stunned, and just stand there staring at one another for a couple of minutes. An old farmer walks out of the woods, and brings them back to reality. The old farmer asks if the men had seen a goat. They both start telling the farmer about how the goat had come running out, and jumped into the hole. The farmer stops them and says, ""nah, that couldn't have been mine. I had my goat tied to a railroad tie"".
