Quickly finish shutting up, everybody. Because A.P. Bio is back!

NBC's wickedly ill-mannered sophomore comedy is gearing up for its (well-deserved) second season, and Glenn Howerton's Harvard philosophy professor-turned-high school bad influence Jack Griffin is more determined than ever to not teach his class of Toledo, Ohio, nerds a lick of biology.

Nor is he, like last year, all that interested in taking any direction from his biggest fan, Principal Durbin (Patton Oswalt). As they say on The Bachelor, Jack is not here to make friends.

Plus, the actor admits his favorite show on TV right now.

In this exclusive first look at the new season, it's revealed that not only has Jack decided to stay in town and continue on at Whitlock High, but that he's also ready to start penning a new book.

In addition, it turns out that the National Honor Society's greatest foe was perhaps more like his students back in the day than he's ready to admit.
