nice
I like your humor style, the script was good. Apart from the slow progression and such it was enjoyable. What I would suggest though is getting some other people to do voices in addition to yourself, so it doesn't just sound like you + other versions of you. Then it would REALLY kill!
I really like how you animated the mouths, and some of the arm movements. The mouths were just so smooth in movement, I really admire you for that. However you may want to make their heads move some more - usually in conversation there are certain syllables and such that have emphasis where people will jerk their heads this way and that - it would really top off the organic style of the toon.
Overall nice job - I look forward to seeing more of you work!
