Sean Kingston comes aboard the S.S. Tipton and promptly falls hard for London. Zack agrees to help the singer out by planning a party where Sean can win her over.

Eureka
9/8c Syfy
When someone utters the phrase, "the past has come back to haunt me," it's usually tied to a bad judgment call, like running into an ex after the messy breakup you initiated or looking at a credit report after years of reckless spending. But in Eureka, phrases tend to take a literal trajectory. In tonight's mid-season finale, Grant and Carter get to relive their very first meeting from a third-person point-of-view, and their trip down memory lane could be catastrophic for the town. — Michael Chant

College Football
7/6c ESPN
ESPN's Friday-night lights shine on tiny Huntington, West Virginia, for the annual Friends of Coal Bowl between the mighty West Virginia Mountaineers and underdog Marshall. Longing for the dominant days of Randy Moss, Byron Leftwich and Chad Pennington, the host Thundering Herd have brought in new head coach Doc Holliday, a longtime West Virginia assistant who's considered one of the game's top recruiters. Doc's first year on the sidelines figures to be painful, however, as the Herd faces senior RB Noel Devine and a top WVU offense after being outgained 529-199 in a 45-7 opening-night loss at Ohio State. — Roger Leister

20/20: A Barbara Walters Special
10/9c ABC
This has been a busy week for Barbara Walters, who underwent heart-valve surgery in May. First, she returned to full-time duty on The View Tuesday; now she's back on her old stomping ground (Walters was a 20/20 co-host from 1984 to 2004), reporting on two girls with a hideous rare disease called progeria. Walters, who's 80, made it to that age they way we all hope to, but the kids she profiles are unnaturally "old": Progeria causes children to age rapidly. These girls were also featured on the December 2009 TLC documentary 6 Going on 60. — Paul Droesch

Four Weddings
10/9c TLC
A second season kicks off, with more ultra-competitive brides attending — and rating — each other's weddings, all convinced that their big day is the one to beat. With a dream honeymoon up for grabs, the ladies are especially critical. Among the featured weddings is a traditional Native American ceremony, nuptials featuring vows in Spanish, and a lavish black-tie affair taking place on a yacht. — Karen Andzejewicz

Martin Lawrence Presents 1st Amendment Standup
11/10c Starz
It's a brand-new season of outrageous funny men and women on this stand-up comedy showcase. What could possibly be different in Season 5 from previous seasons? Comedy is comedy, right? Well, for one thing, there's a new master of ceremonies, make that mistress of ceremonies, as Sheryl Underwood takes over the hosting chores from longtime MC Doug Williams. The opening-night lineup will feature David Raibon, Smokey Suarez and Drew Fraser, so sit back and get ready to give your laugh muscles a workout. — Ray Stackhouse
