Channel Surfing: Dogs, G-men and dancers

Last Comic Standing: Dallas’ Iliza Shlesinger is still in the hunt in this comedy competition, and I’ll bet she just loves tonight’s challenge: "Creating a humorous bedtime story to tell Hugh Hefner’s girlfriends, Holly, Bridget and Kendra, after he tucks them into bed. While the girls — wearing sexy lingerie and sitting in one large, heart-shaped bed — listen with rapt attention, the comics spin their funniest bedtime stories." Is anyone going to notice the comics? 7 p.m., KXAS/Channel 5

Greatest American Dog: Star, the purebred Brittany from East Texas, and Star’s owner, Bill, keep barking along in this canine competition. Tonight, two other (human) competitors look like they’re forming their own brand of puppy love. 7 p.m., KTVT/Channel 11

"G" Men: Turner Classic Movies celebrates the 100th anniversary of the FBI with a bureau-friendly marathon, beginning with this 1935 movie starring James Cagney as a man who was raised by an underworld figure and puts his knowledge to use for the government. Four other movies follow, including 1952’s Walk East on Beacon, a Cold War drama based on an article by J. Edgar Hoover. Begins 7 p.m., TCM

So You Think You Can Dance: The competition is getting tighter for Fort Worth’s Joshua Allen and Carrollton’s Comfort Fedoke, who have made it to the final eight (not, I stress, as partners). Fedoke even bounced back into the competition last week after being eliminated, taking the place of the injured Jessica King. But two more people will be eliminated tonight. 8 p.m., KDFW/Channel 4

Flashpoint: In a move that happened not long before press time, CBS swapped this crime drama with Swingtown, which will now air at 9 p.m. Fridays. In the scheduled Flashpoint episode, an innocent bystander gets caught in a gunfight. 9 p.m., KTVT/Channel 11
