Amazing Race 15
8/7c CBS
The final three teams (Meghan and Cheyne; Sam and Dan; Brian and Ericka) fly from the Czech Republic to Las Vegas, where one duo will win the $1 million first-place prize. Front-runners Meghan and Cheyne look to be the pair to beat, but don't count out conniving gay brothers Sam and Dan or cellar dwellers Brian and Ericka, who always manage to stay one step ahead of elimination. — Tim Holland

Robin Williams: Weapons of Self-Destruction

9/8c  HBO
The last time Robin Williams was on HBO, in July 2002, "weapons of mass destruction" were being floated as a reason for a U.S. invasion of Iraq. While those WMD were never found, you can bet that the comic's arsenal will be fully loaded and deployed in this 90-minute performance in Washington, D.C. Granted, Williams' stand-up routines have never suffered from a lack of ammunition, but tonight his targets will likely include his own recent struggles, including divorce, addiction and open-heart surgery. — Joe Friedrich

Desperate Housewives
9/8c ABC
There's something in the sky heading straight for Wisteria Lane and, sad to say, it isn't Santa's sleigh. Instead, it's a small plane that'll crash into tonight's holiday party, reportedly killing three. And that's on top of the killer already on the loose; the Bolens' murderous secret (so it's Angie!); the Scavo-Solis battle royale; the Bree-Karl-Orson thing; and Katherine's descent into madness. Add it up and there's enough cliffhanger material to last until the Wisterians return in 2010. — Paul Droesch

9/8c Syfy
Nick Willing, who directed a retelling of The Wizard of Oz called Tin Man back in 2007, penned and helmed this reimagining of the famous Lewis Carroll tales following yet another girl who becomes lost in a very strange realm. Caterina Scorsone stars as a full-grown, martial-artist version of the heroine, whilst Kathy Bates turns up as (you guessed it) the Queen of Hearts. Part 2 airs tomorrow night. — Michael Chant

Brothers & Sisters
10:01/9:01c ABC
Justin and Rebecca keep speeding through metaphorical stop signs on the way to their wedding — his dismal midterm-exam results and a baby neither one of them seems 100 percent sure about — and not even a hurricane in Hawaii can blow their plans for a beach ceremony off course. But one Walker who should definitely put on the brakes is Tommy, who makes a desperate move to be near his daughter. Having gambled before and lost everything, what makes him think he'll come out ahead this time? — Joe Friedrich
