Average
Graphics: The graphics weren't that well drawn, but atleast you can tell who/what they are :P Design is definately needing improvement here, in characters and other objects, and try adding a background.
Style: The animation was stiff, try using the ease feature, which would help smooth it out. You synced in time with the music well though =]
Sound: Sound was fine, nothing bad here, good syncing.
Violence: None
Interactivity: None
Humour: Most of the humour was brought about by the song, but you used some of the lyrics well to get a laff =]
Overall: Umm, this needs to be better drawn, and there are tutorials to help you with that, though you don't have to follow them and you can try to get your own style going, but you should follow the great tutorials NG has about animating, they could really help in your submissions.
