An amusing idea and there were plenty of genuine jokes and a funny educational film style that made me keep watching or I would have turned it off the second I saw the title. Nice!
I have a friend who is an amazing musician and he had already written a song that was perfect for this animation. There is plenty of stuff online you can find that's royalty free or cheap as well.
Animation appeals to me precisely because of the limited amount of collaboration necessary.
