That's right, those pesky Chipmunks -- Alvin, Simon, and Theodore -- are back for more mischief and ear-shattering renditions of contemporary pop. The Alvin and the Chipmunks: The Squeakquel trailer kicks off with the Chipmunks, now attending the only high school in America that accepts sweatshirt-wearing rodents, flirting with human teenagers who for some reason cannot resist their charms. (They're so accepted, they've joined the school's basketball and football teams.) But then, as the trailer voice-over ominously announces, there's "one big surprise." Apparently the Chipmunks are entered into some kind of talent show. Who could beat singing chipmunks, Alvin asks? Why (spoiler alert!) three female chipmunks singing and dancing to Beyonce's "Single Ladies," that's who. An energetic twist worthy of M. Night Shyamalan.
