Last week Jack promoted Kenneth The Custodian to president of NBC! The network says of tonight’s “30 Rock” series finale:

In the one-hour series finale, Liz has difficulty adjusting to being a stay-at-home mom while Jack takes stock of his life. Tracy struggles without constant attention from Kenneth as the former page settles into his new job as president of NBC. Jenna prepares an emotional farewell song as the cast and crew reunite for one final "TGS".

Last week Jim made Pam cry and members of the documentary crew found themselves sucked through the “fourth wall.” “1600 Penn” is doing so poorly in the ratings the network decided at the last minute to run two new episode of “The Office” tonight to give the premiere of “Do No Harm” a fighting chance.

NBC says of tonight’s 9 p.m. episode, “Junior Salesman”:

David Wallace tasks Dwight with finding a new part time salesman to fill in for Jim. Dwight assembles a super-team of his cronies, starting with Mose. Pam tries to figure out who will be her new desk mate. Erin tries to find her birth parents with Pete's help.

NBC says of tonight’s 9:30 episode, “Vandalism”:

When Pam asks the office to help her track down the vandal who defaced her mural, Dwight and Nellie spring to action. Darryl has difficulty dealing with the cleanliness habits of Jim in their shared Philly apartment. Meanwhile, Angela grudgingly allows Oscar and Kevin to attend her son's first birthday party.

Premiering tonight:

Do No Harm (10pm NBC)

Returning tonight:

Chef Wanted (10pm Food)
