iCarly
9 pm/ET Nickelodeon
Carly's Web show features a contest with a truly awesome prize: a new car! Soon enough they have a winner, but they seem to be missing the prize. That tiny problem arises because the dealership supposedly donating the vehicle had no knowledge of the contest. Oops! Carly and her friends seek advice from Spencer on how to handle this sticky situation, but Spencer is too preoccupied to help them, as he just realized a movie prop he purchased is a fake. — Jennifer Sankowski

Saturday Night Live
11:29 pm/ET NBC
Hot off the heels of last week's live-wire outing — complete with a Blagojevich skewering, host Neil Patrick Harris in drag, Kristin Wiig portraying a camera-hogging Kathie Lee Gifford, Andy Samberg doing his best Mark Wahlberg ("Say hello to your mutha for me") and even a Liza Minnelli cameo — it seems everything's coming up Rosario. Actress Rosario Dawson, currently seen in the film Seven Pounds with Will Smith, serves as tonight's host, while Seattle indie-rock practitioners Fleet Foxes take to the music stage. — Dean Maurer

Austin City Limits
9 pm/ET PBS
Foo Fighters, the acclaimed alternative pop-rock band led by one-time Nirvana drummer Dave Grohl, deliver a dense sonic set that's punctuated by the Who's "Young Man Blues," old tunes and the relatively new songs ("But, Honestly," "The Pretender") from their 2007 Echoes, Silence, Patience & Grace album. — Jeff Gemmill

Solitary
9 pm/ET Fox Reality
Unlike most reality contests, contestants here (they're known as "guests") aren't voted off; they vote themselves off. There's no backbiting, either, because they compete in isolation, interacting only with "Val," their faceless — and very nasty — taskmaster. The challenges Val assigns are just as nasty, and in tonight's third-season opener, they begin right off the bat. And one more thing, guests will share their isolation pods this season. — Paul Droesch

H2O
9 pm/ET Nickelodeon
Zane gets excited when he hears about a treasure buried at sea, and he decides to up his chances of finding it by asking his mermaid friends for help. The girls, of course, say yes, but even mermaids can run into trouble in the water, which is what happens to Rikki, who gets hurt during the search. Meanwhile, conniving Charlotte is up to her old tricks as she works on a plot to keep Lewis away from the girls. — Jennifer Sankowski
