Class is about to be back in session in Greendale Community College.

On January 2, NBC will air the first two episodes of Community Season 5, following a lengthy hiatus for the series and a really lengthy hiatus for creator Dan Harmon:

He returns to the helm after being forced out at the conclusion of Community Season 3.

What will the opening pair of installments - titled "Repilot" and "Introduction to Teaching," respectively - entail? We have no idea, really, except for Jeff in a suit... Abed with some crazy hair... the debut of Jonathan Banks as a professor... and a murderer rat.
