Great news for fans of NBC Thursday night comedy!  In addition to giving Parks & Rec the go-ahead for a third season, NBC has decided to renew the rest of its Thursday night lineup, including freshman comedy Community and old staples like The Office and 30 Rock.

While we’re on the subject of NBC comedies, it’s be let known that two new characters are joining the already-strong cast of Parks & Recreation.  Actor Rob Lowe will be leaving his current post at ABC’s Brothers & Sisters and will join Parks & Rec at the end of this season; series creator Michael Shur hints Lowe will be on board for “a number of episodes stretching into Season 3.”  Funnyman Adam Scott (you know him from Step Brothers; he played Brennen’s brother Derek) will also become a recurring character who will enter the scene towards this season’s end.  Lowe and Scott will likely be welcome additions to Pawnee’s colorful, hilarious cast.
