NBC Slates Full Hour of '30 Rock' for Tonight

On the February 9 hourlong block of '30 Rock,' Criss (James Marsden) and Liz (Tina Fey) decide to celebrate Valentine's Day, but they need to buy a dining room table first. Jack (Alec Baldwin) entertains his mother-in-law, Diana (guest star Mary Steenburgen), as Jenna (Jane Krakowski) frantically looks to Pete (Scott Adsit) to fill in last-minute as the producer of her first live performance on "America's Kidz Got Singing."

Back at the office, Tracy (Tracy Morgan) and Frank (Judah Friedlander) try to help Lutz (John Lutz) find someone to spend Valentine's with.
