GMod is a creativity toy, one that you can use to create weird and wacky scenarios for amusement. It's not supposed to make sense, it's something to goof around and have fun with. I don't really play it a lot, I don't have the creativity to do anything with it. I don't like every single video that people make of it, though some make me laugh. There's nothing wrong with it, as a game, a tool, or as a subject for videos. To each their own.
