These two guys out hunting find a hole in the woods that's about three feet across, but it's so deep that when they drop a rock, they hear no sound. So they drop a bigger rock, but they still hear nothing.
So they go looking for something larger, and they find a railroad tie, haul it over to the hole, and heave it in. It also disappears without a sound.
Suddenly a goat comes running up at about sixty miles an hour and dives headfirst into the hole. And there's still no sound. Nothing.
Suddenly a farmer appears from the woods and says, "HEY! You fellas seen my goat around here?"
And they say, "Well, there was a goat just ran by here real fast and dove into this hole here."
"Naw," says the farmer, "that couldn't be my goat. My goat was tied up to a railroad tie."
