Oh those Wacky rich people! :P
I found this rather humorous. Poking fun of snooty rich kids never gets old and should always be encouraged - well if you ask me that is. :P
Strangely enough, it appears that the sound sync problem actually added to the overall feel of the movie in a strange sort of way - it reminded me of those badly dubbed martial arts movies of the 60's and 70's. That combined with the high degree of tweening - It reflected the subject matter quite nicely indeed.
Either way - sound sync problem or not, your heart was in the right place. Good job. :3
