“My Name Is Earl,” “30 Rock,” “The Office” and “Scrubs” (starting at 8 p.m., NBC): NBC is back on the comedy block. The network is rolling out post-strike episodes of “My Name Is Earl,” “30 Rock,” “The Office” and “Scrubs” tonight. The Writers Guild of America strike caused a delay in new episodes for months. Their return is certainly a reason to rejoice. “Earl” has already gotten back into the action. The 8 p.m. comedy with Jason Lee as a lovable loser premiered an hourlong episode on April 3. Now with the arrival of “The Office,” “30 Rock” and “Scrubs,” NBC’s beloved comedy block is finally complete. What you can expect:

On“Earl,” our hero remains in a coma, dreaming his life is a sitcom. In this week’s “dream” episode, Earl awaits the birth of his son. Randy wants to fix Earl’s “broken” karma by making things right with the family from “American Chopper.”

Over on “30 Rock,” Jack (Alec Baldwin) is excited over his idea for a new reality show about hot mothers living on an island. His ego is bruised, though, by a gossip-column item.

“The Office” centers on Michael (Steve Carell) and his girlfriend, Jan, hosting a dinner party that Jim and Pam must endure. Matters get worse when obnoxious couple Andy and Angela are also invited.
