The gang at "30 Rock" returns from their summer hiatus.

Jack also tells her about his plan for SeinfeldVision, which entails using NBC-owned footage from Seinfeld's show and inserting him into NBC's current shows. Jerry Seinfeld (Guest Star Jerry Seinfeld) shows up at Jack's office upset about SeinfeldVision. Meanwhile, Jenna (Jane Krakowski) has gained weight over the summer after doing the musical, "Mystic Pizza: The Musical!" and Kenneth (Jack McBrayer) becomes Tracy's (Tracy Morgan) office wife when Tracy's wife kicks him out.
