In belated commemoration of Alvin's CGI debut, I searched for some old school AATC and came across this. I had completely forgotten about the Chipettes!...and how....um....well, we're completely okay that they move like that, right? And we don't care that we get to see their underwear...like, a lot?
Moreover, what a weird concept - mutated chipmunks in floor-length sweaters that sing.
(By the way, as of this posting, Alvin and the Chipmunks (2007) has a 25% freshness rating on Rotten Tomatoes.)
