There's these two guys standing by a huge hole in the ground having a beer. It's too dark to tell how deep it is, so one guy throws a rock in the hole, and waits for the sound of it hitting the bottom. Nothing. So, the second guy throws a full can of beer down the hole, and waits for the sound of it hitting. Still nothing. So the first guy grabs a railroad tie, and pushes it down the hole. Nothing happens still. About 10 seconds later, this tiny Yorkshire Terrier comes running faster than a car, and jumps into the hole. Well, the guys are stunned. About a minute later, this old scottish guy comes over, and in a thick accent, he asks "have ya seen ma weeeeeee yorkshire terrier?" To which one of the guys replies "ya, he just ran like hades past us and jumped down the hole over there." The scotsman replies "nah, that wasn't him, he's 15 years old and can barely walk, and anyway, I tied him to a big friggin railroad tie"
