So these two bumpkins are walking along and find the biggest, deepest hole either has ever seen. They throw a rock in to gauge the depth - silence. They heave in a bigger rock - silence. They scout around and find a railroad tie, throw *that* in - still silence. They're looking at each other, scratching their heads, when along comes a goat, runs to the hole, jumps in, and disappears. Now the two are standing there with their mouths open. A bit later, along comes a farmer, asking Have you seen my goat? Well, says one, we saw *a* goat - it ran up and jumped in this here hole! Strangest thing you ever saw! Nah, says the farmer, that can't be *my* goat. *My* goat was tied to a railway tie.
