I don't really find this funny, but I see what you're going for. It kind of ruins it that you see your watch and arm a lot. Also, the background doesn't really make sense. The noises you make while the hands are walking are weird and kind of unnecessary and the sound effects are jarring. I think if you put a little more effort into the background and the actual movements (eg. not have the hands walk off backwards) it would be a lot better. I also don't understand why the last hand gets shot! Definitely some potential there but it's not quite there yet.
