Really great! Your movie was very original and funny. After it ended I was laughing for good ten minutes!
About the art - next time I advice to research some anatomy and basic human build on internet, or just look at people or yourself in the mirror and draw. I know it's hard to animate and draw in flash, but try to give it a bit more work. Also try removing outlines at bits where body parts merge together, on the neck, head, arms, hands and stuff like that.
Otherwise, really great! You deserve a 5!
