Alec Baldwin

NBA All-Star Saturday Night
8:30 pm/ET TNT
Before you see the fan-selected, all-around best of the best in tomorrow's All-Star Game, check out some of the best of various aspects of the game. Individual and team events include the skills challenge and shooting stars competition. Also, Toronto's Jason Kapono looks to three-peat in the three-point shootout against such long-shot specialists as Rashard Lewis of the Magic and Roger Mason of the Spurs. And Dwight Howard, take note: the slam dunk title has not been successfully defended since Jason Richardson won back-to-back in 2002-03. And he was the first since some guy named Jordan did it in 1987-88. —Brendan Curley

Christopher Titus: Love Is Evol
10 pm/ET Comedy Central
For many folks, Valentine's Day is a time of romantic pursuits, sentiments of profound devotion and telling that special someone just how much you love them. For Christopher Titus, however, it's likely to conjure up thoughts of suicide, murder and all-around misery. So grab that half-eaten box of chocolates, sit back and catch the premiere of the hard-boiled comic's latest laughfest. But keep an eye on your mate, too, just in case he or she gets any ideas. —Joe Friedrich

Saturday Night Live
11:29 pm/ET NBC
It's a Valentine's Day affair, and Alec Baldwin clearly has love for the late-night show. Baldwin, no stranger to 30 Rock, returns as the host for the 14th time, challenging crowning champ Steve Martin's hosting record. (Martin hosted for a 15th time on Jan. 31.) Love will be in the air and hearts will flutter  — especially with poppy, teen dreams Jonas Brothers taking to the music stage. Listen carefully and you can hear the tween and teen girls screaming already. —Dean Maurer

Austin City Limits
9 pm/ET PBS (check local listings)
Canadian folk-pop chanteuse Sarah McLachlan performs her greatest hits, including the reliables "Building a Mystery" and "World on Fire." The reason to tune in, however, is the performer who follows: British pop-soul sensation Duffy, whose captivating retro sound channels Dusty Springfield, Petula Clark and Motown. The hypnotic "Rockferry" kicks off her five-song set, which also features the teary kiss-off "Warwick Avenue" and claws-out "Rain on Your Parade," a delicious update of Nancy Sinatra's "These Boots Are Made for Walkin'." —Jeff Gemmill

Before You Say 'I Do'
9 pm/ET Hallmark
We've all heard that timing is everything. Well, tonight's original movie proves the adage true when it comes to love. David Sutcliffe plays George, a man whose girlfriend (Jennifer Westfeldt) won't accept his proposal because she was badly burned by her first disastrous marriage. A twist of fate  — namely, a car accident — sends George back in time and gives him the opportunity to stop his one true love from marrying the wrong man. —Brie Hearn
