Titanic's Final Mystery (8pm, Smithsonian) - A new documentary investigates a century of theories behind the sinking of the Titanic and uncovers new forensic evidence that proves the most likely theory for the disaster.

God is the Bigger Elvis (8pm, HBO) - A documentary about a famous movie star from the late 1950s and early 1960s who walks away from Hollywood at the height of her fame to become a cloistered Benedictine nun. Here's more on Dolores Hart's fascinating story.

Community (8pm, NBC) - The war between Abed and Troy intensifies, prompting Jeff to try to negotiate a truce between the former best friends while the rest of the group choose sides.

Person of Interest (9pm, CBS) - The Machine produces five numbers linked to New York's crime families, which prompts Reese and Finch to suspect that Elias has plans for his competition.

Scandal (10pm, ABC) - An entertaining new series in which a former White House communications director, played by Kerry Washington (right), runs a Washington, D.C., crisis-management firm. Here's my "Scandal" review.

Being Elmo (10pm, UNC-TV) - This Independent Lens documentary, narrated by Whoopi Goldberg, tells the life story of Kevin Clash, the puppeteer behind the popular Sesame Street character, Elmo. It's pretty enchanting. Adrienne has a full review.

Awake (10pm, NBC) - Michael tries to end a delicate hostage crisis and negotiates with a patient who is threatening to blow up a mental hospital. Meanwhile, his sleepless nights adversely affect his life and work.

This is kind of unreal. Michaele Salahi, half of the White House party crasher duo and participant in the upcoming season of Bravo's "Real Housewives of DC," appeared with her "Housewives" cohorts on "The View" this morning and things got a little out of hand.

There were some grumbling about whether President Obama should have appeared on "The View" today.

After watching, I can't say a bit of dignity was visibly lost. The ladies took the event quite seriously; besides bringing in Barbara Walters to give them news credibility, Sherri Shepherd wore her most dignified hair, a big old bun.

Were the questions tough? Nah. But the president didn't talk about whether he wore boxers or briefs. Indeed, I'm pretty sure he accomplished exactly what he wanted. And no, Joy didn't kiss him, and yes, Elisabeth did attempt to go hard.

Last season, I tuned into an episode of 'The Cleaner' because it stars Benjamin Bratt.

I have love for Bratt because of his stint on 'Law & Order'; I think his character's (Rey Curtis) partnership with Lenny Briscoe may be my favorite pairing.

Benjamin isn't hard to look at either.
