Alvin and the Chipmunks 2

When the Chipmunks have spent long enough hanging around the house, David sends Alvin, Simon, and Theodore off to school, saying "it's good for them." Little does he know that the Chipmunks feel like "chipmunks out of water" because of all the humans around.

Meanwhile, when Ian, bemoaning the financial blow of his loss of the Chipmunks, searches the world for animals who can sing and dance, he happens upon the Chipettes (Anna Faris, Christina Applegate, Amy Poehler) and can't wait to make them famous and get revenge on the Chipmunks.
