* So You Think You Can Dance (9 pm/ET Fox)
Only Mary Murphy truly knows what her Hot Tamale Train is all about, but tonight's first results show of the season will find two of the Top 20 dancers getting off at the next station. Before that happens, however, the bottom three couples will dance for their TV lives in solo routines, and if that's not enough sizzle for you, rapper Sean Kingston performs "Fire Burning" from his second album, Tomorrow.
* American Chopper (9 pm/ET TLC)
The Teutuls are no strangers to family conflict, so they should have plenty in common with tonight's featured client: Jon Gosselin, star of Jon & Kate plus 8 and recent tabloid target. Jon has commissioned OCC to build him a custom chopper, so Senior, Junior and Mikey take a trip to the Gosselins' Pennsylvania home to get a better idea of what he wants. And the guys get on Kate's good side by bringing her a pink scooter of her own.
* She's Got the Look (9 pm/ET TV Land)
The search for modeling's new face - over-35 division - is back for a second season of smiles, tears, laughs and fears. Host Kim Alexis guides 20 women through a grueling competition that rewards the winner with an exclusive contract and a photo spread in Self magazine, and as an extra incentive, also comes with a $100,000 prize. Tonight the hopefuls move into the New York City loft they'll share for the next seven weeks, and begin their quest to redefine what it means to be a "model" citizen.
* Raising Sextuplets (10 pm/ET WE)
There's a new family of multiples in town. Spun from WE's 2008 special OMG! Sextuplets!, this series follows first-time parents Bryan and Jenny Masche as they wade through the chaos of parenting six toddlers. In tonight's premiere, just giving the dog a bath turns into an ordeal for the gang. Jenny is also preparing to return to work and training for a marathon. Bryan, on the other hand, hasn't sprung back into shape as quickly as his wife and struggles to shed sympathy weight he packed on during Jenny's pregnancy.
* Tosh.0 (10 pm/ET Comedy Central)
Last week's premiere gave us a taste of what to expect from comic Daniel Tosh's new show, which uses the boob tube to show us what YouTube - and everything else on the Internet - has to offer. OK, so there weren't any sneezing pandas, but there are nine more episodes to go. And if you thought the Afro Ninja's Web Redemption was touching last week, wait until Miss Teen South Carolina takes another stab at world geography.
