Do No Harm will not be the only NBC Thursday midseason series MIA next week. Fellow low-rated newcomer 1600 Penn will be benched next Thursday for a new Office. I hear the move was prompted by The Office Valentine Day episode, which NBC brass loved. It came in supersized, so a decision was made to expand it into two back-to-back originals. For now the plan is for 1600 Penn to return the following Thursday, Feb. 21. 1600 Penn is coming off a series low 1.1 18-49 rating last night, down 15% from its previous original. It served as a lead-in to Do No Harm (0.7), which got the axe earlier this afternoon.
