Community returns with more than just a new episode next week.

The hilarious NBC sitcom airs its first installment of 2010 with a special guest star: Jack Black.

The movie star portrays a flaky classmate that's been stalking Jeff and the entire clique.

“There’s this awesome way we go back and show you that he’s been in all of our classes,” says Joel McHale. “We just didn’t realize it... This character was perfect for Jack. He makes so much out of every word that it was inevitable that he’d be terrific."

As if Black's appearance (along with the typical abundance of Community quotes) isn't enough to draw you in on January 14, consider this tease: Britta in a cheerleading outfit.
