The Greendale gang is keeping it weird in the trailer for “Community” season six

“Community,” rescued from cancellation by Yahoo, returns for its hard-won sixth season on March 17th. Here’s a first look at the Greendale gang back in action, featuring new cast members Paget Brewster as consultant Frankie Dart (aka "new Shirley") and Keith David as Elroy Patashnik, a retired inventor looking for a fresh start (as he puts it: “I have a brain the size of Jupiter, I’m nobody’s fourth Ghostbuster”). The trailer also features blood oaths, dogs getting degrees, and a spot-on "Avengers: Age of Ultron Parody." Check out the antics below:
