Two guys are hiking in the woods...

...and they come upon a big hole in the ground.

One of them grabs a rock and drops it and they wait and they wait and they wait and they never hear it hit the ground. So they go over to a big boulder and roll it over to the hole and shove it over the edge. And wait and wait and wait and they never hear hit bottom.

They're amazed. How far down does this thing go?

One of the two guys says, "Hey, look at that." And they grab this huge railroad tie lying there and drag it over to the hole and they just fire this railroad tie right down the middle of that hole. Again, they're waiting and waiting and waiting - nothing happens.

Suddenly a goat comes running by them and just dives head-first down the hole. They start laughing, what was that?

A few minutes later a guy comes walking up to them and says "hey, can you guys help me out? I'm looking for my goat."

The guys look at each other, then look at the man and say "you know what, this is really strange, but this goat just came running by us and jumped into that there hole."

The man says, "Nah that wasn't my goat. My goat was roped to a railroad tie."
