Cake Boss

Cake Boss
9/8c TLC
Peppermint, birthdays and polar bears, oh my! Buddy makes a cake for the Coney Island Polar Bear Club, where he's invited to take a swim with the furry creatures. On top of that, Buddy's youngest son wants an ice-cream cake for his birthday.

Last Comic Standing
8/7c NBC
The stand-up talent contest opens its seventh season, and it's a matter of laugh or death for a new crop of competing comedians hoping to avoid elimination and win top comic honors. The epic star search for America's funniest jokester kicks off with a two-hour edition featuring open auditions and a comedy showcase in Los Angeles. The summer series comes with a few changes: Craig Robinson, a deadpan delight as Darryl the warehouse denizen in The Office, is the new emcee, following the footsteps of former series hosts Jay Mohr, Anthony Clark and Bill Bellamy. In addition, Andy Kindler, Natasha Leggero and Greg Giraldo serve as judges and talent scouts. — Dean Maurer

Neighbors From Hell
10/9c TBS
TBS gets in toon with a freshly minted animated comedy from the producers of "South Park" and Madagascar" about neighbors from hell---literally. The heat is on when Satan opens up his fiery underworld and sends the devilish Hellman family to Earth to pose as suburbanites in Texas. It seems humans are drilling into their hellish realm, and the Hellmans are enlisted to stop them. Among those lending their voices: Will Sasso as father and hubby Balthazor, Molly Shannon as his wife, and Patton Oswalt as the family's cerebral pooch. — Dean Maurer

Persons Unknown
10/9c NBC
Seven strangers are abducted and thrown together in a deserted town in the pilot episode of this new mystery series from The Usual Suspects writer Christopher McQuarrie. The group members don't know why they've been taken or what they'll have to do to gain freedom, but they soon realize that someone's watching them through security cameras perched all over town. The mystery deepens when one woman receives an ominous message in her fortune cookie: "Kill your neighbor, and you'll go free." — Brie Hearn

Nurse Jackie
10/9c Showtime
Jackie's personal and professional lives have been colliding all season, and now she has no place to hide as Season 2 comes to a close. As Jackie herself puts it: "It's all crashing down around me." She has some serious explaining to do at home since Kevin isn't happy she took the money from O'Hara, and work isn't much of a haven since that drug dealer is still after her and O'Hara isn't too pleased that Jackie lied to her about the MRI. Nurse Jackie could probably use some divine intervention, so it's a good thing "God" makes an appearance. — Helen Danicki

The Bachelorette
8/7c ABC
Ali still has a Chris logjam (H. and L.), but there's just one Craig left in the field of 14, as dental-supply salesman Craig M. ("dangerous person") went roseless after nearly coming to blows with weatherman Jonathan, who issued the "dangerous" alert to Ali. But it's Justin who takes tonight's boldness prize when he hikes to the mansion in a display of ardor, delaying Ali's one-on-one with Hunter. But she and Hunter do end up in a hot tub. There's also a tightrope walk (seriously), the Barenaked Ladies and, when the evening's over, 11 guys with roses. — Paul Droesch

Lie to Me
8/7c Fox
No Fox exec would dare call this psychological crime drama a hit in front of deception specialist Cal Lightman (Tim Roth), but it has been picked up for next season. It's also beginning a run of a dozen new Season 2 episodes, starting with this one, as Cal  tussles with a charming and brilliant psych graduate student he suspects of being a murderous psychopath. The young man's professor (who has a romantic past with Cal, naturally) disagrees.  Who do you think is right? In the episode's other story line, Howard Hesseman guest stars as a science teacher who says he saw a UFO. — Paul Droesch
