And our North Carolina home boy has another rough go of it as he gets caught between the ever-battling Bickersons -- comedian Lisa Lampanelli and former Miss Universe Dayana Mendoza.

This week's task is to come up with a jingle for the Good Sam Club, which is apparently for RV enthusiasts. (We'll pause briefly for you to conjure up the highly unlikely image of Donald Trump cruising the backroads in some sort of gold-plated Winnebago with a big ole "T" on it.)

Because Clay, center, was project manager last week, he agrees to let Dayana, right, handle it this week. Hmmm, this could be a problem, seeing as how he's a professional singer and she knows so little about music that Clay actually has to explain to her that a jingle has nothing to do with "Jingle Bells." Still, he and Lisa, left, try to teach her. And for a while, they listen patiently while Dayana suggests a jingle that sounds like Duran Duran. Cause we all know RV drivers can't get enough "Hungry Like the Wolf."

Veep (10pm, HBO) - The Veep is unexpectedly called to the White House Situation Room and later falls victim to a stomach bug that's going around.

Last night's "Celebrity Apprentice" was really too close for comfort for Clay Aiken fans. The Raleigh recording star came unbelievably close to being fired by Donald Trump after Clay's team lost the night's challenge. I personally thought Clay was a goner.

But let us back up a little before we get to the boardroom dramatics...

The episode began with Aubrey O'Day and Arsenio Hall both separately -- and hilariously -- assessing what's left of their team (it's the two of them plus Teresa Guidice).

Arsenio: "I'm stuck with two women now. One's damn near genius and the other is damn near not." I'm sure Arsenio meant to say "evil genius" in describing Aubrey. Obviously a slip.

Aubrey: "Arsenio is shifty and Teresa's not strong."

Okay, so -- go team!

Thanks to "Celebrity Apprentice," we now know that Clay Aiken can do almost anything.

He can sing (of course) and he can act. He can also write, direct, design and produce.

But the coolest thing Clay has done so far this season is display his mastery as an improvisational puppeteer.

For this week's challenge, the "Celebrity Apprentice" teams had to put on a show for the audience of Henson Alternative's Stuffed and Unstrung puppet show (which has a show in Durham this week!). Brian Henson, son of Jim, is the force behind "Stuffed and Unstrung," along with Patrick Bristow, who you may recognize from Ellen Degeneres' old sitcom "Ellen." 

The teams had to design and build their own puppets, get some quick lessons on how to handle the puppets (which Clay didn't need -- thank you very much, Vacation Bible School!) and a rundown on the rules of improv, and then finally, perform the show.

Mad Men (10pm, AMC) - Tonight's cryptic episode summary: Lane makes an interesting friend and Pete plays host to an assortment of guests.

Girls (10:30pm, HBO) - In the premiere of a new comedy about a group of twentysomething women navigating life in New York, Hannah (Lena Dunham) gets shattering news from her parents and then loses her unpaid internship. This series is crazy good. Here's my full review.

As promised, lots of fighting tonight! The show started with Arsenio Hall still ranting about Aubrey O'Day. When Lisa Lampanelli came in and heard the language he was using to describe Aubrey, she calmly suggested Arsenio might want to reconsider his choice of words.

Nah, just kidding. Lisa totally went off on Arsenio, screaming at him and calling him out for his language (b-word, w-word). Arsenio -- very correctly -- pointed out that Lisa is about the last person on earth who should be telling someone what kind of language to use. Lisa -- also correctly -- pointed out that Arsenio could be trashing his image and career by alienating women at home.

Lisa also made a comment to Teresa Guidice about how she felt bad for Aubrey being ganged up on by "those two" -- and I think she meant Arsenio and our boy, Clay Aiken, left.

Titanic: The Final Word with James Cameron (8pm, NGC) - National Geographic Explorer-in-Residence James Cameron, who also directed the blockbuster "Titanic" film, assembles the world's leading experts on the sunken ship to investigate lingering mysteries of how and why the "unsinkable" ship sank.

Meanwhile, Kevin and Jackie have split and Jackie's troubling encounter with a fellow drug user (Green Day's Billie Joe Armstrong) helps propel her into rehab. I got to watch nearly the whole season and it's worth sticking with.

Great Expectations (9pm, UNC-TV) - The conclusion of newest version of the Charles Dickens classic. Tonight, Pip is in London, where his guardian explains his allowance. In time he learns the ways of gentlemen, and he falls further in love with Estella.

The Killing (9pm, AMC) - Sarah searches for Rosie's backpack, while Richmond comes to grips with his diagnosis of paralysis, and Mitch finally turns up.

Keep reading for more shows.

The music ended for two contestants on last night's super-sized "Celebrity Apprentice" episode, both victims (in my humble opinion) of poor team leadership. But we'll get to that later (don't worry -- Clay Aiken is still safe). The most interesting part of last night's show was watching Arsenio Hall's slow burn build to a full inferno of hate, which engulfed his toxic -- but entertaining -- teammate Aubrey O'Day.

Just, wow. It's saying something when the person on your team most famous for crazy, violent freakouts (table-flipping reality star Teresa Guidice) is frightened by your outburst and thinks you might be unstable.
