Dancing With the Stars
8 pm/ET ABC
The eighth season kicks off with two celebrities already out of the competition. Announced participants Jewel and Nancy O'Dell dropped out on Thursday due to injuries they suffered during training. But the show must go on, and the remaining celebs — including Denise Richards, Lil' Kim, Shawn Johnson and Lawrence Taylor — should still be eager to strut their stuff and become the next Brooke Burke. And romance is definitely in the air this spring, as two real-life couples take to the floor: Julianne Hough pairs up with her boyfriend, Chuck Wicks, and pro dancer Maksim Chmerkovskiy tries to outlast his fiancée, fellow pro Karina Smirnoff. — Jennifer Sankowski

Heroes
9 pm/ET NBC
Now that Sylar's image of his father has been, errr, tarnished, it's probably safe to assume their reunion won't be picture-perfect. After a long search, the baddie finally finds his dad (John Glover) tonight, but the meeting doesn't go the way he'd imagined. Elsewhere, the Hunter continues to be a thorn in Nathan's side as he tries to usurp Nathan's operation and uncover Petrelli family secrets (and, boy, are there plenty of those). — Brie Hearn

How I Met Your Mother
8:30 pm/ET CBS
That '70s Show's Laura Prepon is still getting stuck in the past — but at least she's moving up a few decades. Prepon plays Ted's former flame from college, with whom he reunites. Nice for Ted, but not for Lily and Marshall, who reveal how much they detested the snooty woman. — Bill Ecklund

Castle
10:02 pm/ET ABC
Who says crime doesn't pay? Richard Castle (Nathan Fillion) and Kate Beckett (Stana Katic) both make a successful living off of it in ABC's new crime drama. The twist? Celebrity mystery writer Castle and hard-nosed detective Beckett team up to catch a serial killer who has been plagiarizing in the worst way: bringing Castle's fictitious murders to life in New York City. Faster than you can say "moonlighting," sparks fly between the two charming leads. — Rhoda Charles

Anthony Bourdain: No Reservations
10 pm/ET Travel
Anthony Bourdain first visited Vietnam in 2000, and he's longed to live there ever since. On his return to Saigon, he meets up with his former boss, the always adventurous Philippe Lajaunie. The two explore the flavors, sights, sounds and smells that keep them coming back for more. Then, the host thinks about turning his dream into a reality and checks out potential properties in Hoi An, a picturesque village filled with rice-paddy fields, water buffalo and pointy hats. — Karen Andzejewicz
