I've posted this before, but not in its Youtube version. This was our group project for the animation class I took at Foundation University way back in 2005. (Has it been that long?)
It was a two-week rush to get this done, and I suppose what's incredible is that in the end, it's only a 35-second video. But it was fun doing it, and ours was the only group that managed to string together the entire gag. Well, some parts were left without any inking or coloring, but it was my idea to put them in anyway.
The team that stayed with Foundation did come up with a more polished version (one that included falling teeth) but I don't have access to that anymore.
