Hahaha. Cool.
Good Points:
The voices were good, very clear and suited the characters. The idea was pretty decent aswell, and it had a few funny jokes and refrences in there. The lip synching was perfect too :)
Bad Points:
The actual animation was pretty bad, meaning the movement of the characters was pretty jerky. Putting some tweens in there would have helped a lot or atleast a frame between the two movements would make it a whole deal better and smoother.
Overall:
It was enjoyable to watch. I can see you've put a lot of effort into this and it's payed off. I'm going to go check out your other stuff now.
