2 guys are walking through the forest, and come upon a wide hole in the ground with no apparent bottom. One guy picks up a rock, tosses it into the hole, and waits for the rock to hit bottom. "Wow, this hole must be really deep, I never heard it hit bottom!". The next guy finds a large stick, tosses it down with the same result. "Wow, I wonder how deep this hole really is?" They search around a bit, find a railroad tie, drag it over to the hole, and tip it in as well. It bounces off the sides a bit, but, again, never hits bottom. They stand and stare into the hole, bewildered by how deep it must be. "Crash, crash, crash!" They turn around, and see a large goat flying through the underbrush, comes past them and dives into the hole! "Did you see that goat?!! What could possibly be in that hole?" While pondering all this, another man comes wandering around, and asks "have you guys seen a goat around here?" "Yeah! One just ran through the forest and jumped down into this hole!" Guy says "no must be a different goat, mine was tied to a railroad tie"...
