On TV this Thursday: Valentine’s Day at 30 Rock and Seattle Grace could not be more different, girls get wild at a Secret Circle slumber party, the Swamp People return and more. As but a supplement to TVLine’s original features, we’ve picked nine programs to keep on your radar.
8 pm 30 Rock (NBC) | Double episode! Jack entertains his mother-in-law (guest star Mary Steenburgen, Bored to Death); Tracy and Frank try to help Lutz find someone to spend Valentine’s with; Criss and Liz can’t celebrate until they buy a table.
8 pm The Big Bang Theory (CBS) | After Sheldon is forced to take vacation, he goes to work with Amy in her neurobiology lab; Bernadette tries to get Howard to sign a pre-nup.
8:30 pm Rob (CBS) | Rob asks Hector to teach him Spanish – in secret – so he can understand what Maggie’s family is saying about him. Let’s hope this turns out better than it did for Elaine Benes and her Korean manicurists.
9 pm Grey’s Anatomy (ABC) | For Valentine’s Day, Callie surprises Arizona with a romantic evening, Derek and Meredith spend the night out and Ben proves to Bailey that he knows her better than she thinks. (But it’s not all fun and games — check out our first look video in this week’s Spoiler Alert.)

9 pm Swamp People (History) | Season 3 premiere: The next 30-day hunting season kicks off with a “Gator Gold rush.” (P.S. If you’re near NYC, Chelsea Market is converted into a makeshift swamp for the week.)
9:30 pm Up All Night (NBC) | When Ava and Kevin have an epic blow-out, Reagan and Chris find themselves wistful for relationship drama — and unintentionally end up creating some of their own. (Watch exclusive clip!)
10 pm The Mentalist (CBS) | Jane tries to prove a murder trial defendant has been wrongfully accused before time runs out. Diane Farr (Numb3rs) and Samaire Armstrong (Dirty Sexy Money) guest-star.
