Emmanuelle Vaugier and Gary Sinise, CSI: NY

CSI: NY
10 pm/ET CBS
Hill Harper's Dr. Hawkes is front and center in tonight's head-scratcher, which involves two murders, the return of a serial rapist and dozens of brides-to-be gone wild. First, a woman is found dead at a bridal shop, after a mob of ladies storms the store searching for a killer dress at a to-die-for price during an annual sale. Across town, a subway musician is raped and murdered by the same person who raped Hawkes' girlfriend nine years ago. Even more bizarre is the fact that the two deaths are connected. — Tim Holland

Top Chef: New York
10 pm/ET Bravo
Last week introduced Toby Young as the newest judge. (He replaces Gail Simmons for the rest of season.) The bespectacled, stern-faced Brit backed up his nasty reputation, criticizing some cuisine as "weapons of mass destruction" and "cat food." Meeeow! The show will surely get cattier with Mr. Young in the kitchen. But there will be some fresh air tonight: The chefs journey to the country to gather fresh ingredients, then serve up a food-fare feast to farm workers. — Dean Maurer

Lost
8 pm/ET ABC
Season 5 begins here next week, so if you want to catch up, here's a repeat of last season's final three hours. They chronicle Oceanic 6's tortuous journey home (bullet holes in chopper gas tanks and exploding ships do make for tough travel), plus plenty of foreboding, including the creepy final funeral-parlor scene. What's up? "All of you have to go back," Ben tells Jack. Easier said than done, Ben. For starters: What did you do with the island? — Paul Droesch

Make 'Em Laugh: The Funny Business of America
8 pm/ET PBS
Wild and crazy guys that eat live chipmunks and/or wear two socks on one foot kick off this history of American hilarity, hosted by Billy Crystal, which breaks down the funny business by genre. "Nerds, Jerks & Oddballs" highlights comedic outsiders, including such greats as Harold Lloyd, Bob Hope, Phyllis Diller, Andy Kaufman and the silliest serious man to walk across a stage, Steve Martin. Then, "Breadwinners and Homemakers" hones in on domestic comedies, including the groundbreaking sitcoms The Goldbergs, I Love Lucy and Roseanne. — Jeff Gemmill
