I guess there have been worse
The animation was not the worst I had ever seen, but you really need to work on a joke. The trouble with this is that it is just way too short. If you are making something like this, the animation has to be a lot better and not just mediocre. I suggest making it longer, although at least you put that preloader in the beginning, which is something I could not do. Do you need to have flash to use that preloader? Anyway, work on better delivery and more tension built up.
