Daytime favorite Tristan Rogers reprises his role as superspy Robert Scorpio during the second season of "General Hospital: Nightshift" (beginning 11 p.m. EDT Tuesday, SoapNet).

Bill Engvall doesn't envy being the Blue Collar Comedy Tour's trophy husband.

"Being on Blue Collar was like being married to a rich girl," he says. "It was great, but after a while you want to show people you can earn your own living."

Thus, "The Bill Engvall Show," airing 9 p.m. EDT Thursdays on TBS, is his ticket to career independence.

The colorful characters of "My Name Is Earl" are winging it without a script for the first time.

"Earl" actors -- including star Jason Lee -- will play "Celebrity Family Feud" (8 p.m. EDT Tuesday, NBC) in character. This will mark the first time the cast has worked together in character without a script.

When Mitch Rouse -- who co-created the outrageous "Strangers with Candy" and "Exit 57" -- wanted to grow his own sitcom, he headed to his back yard.

Al Roker, the jolly weather personality from the "Today" show, is reigniting the Feud.

Roker will host the star-studded new "Celebrity Family Feud" (8 p.m. EDT Tuesdays, NBC). The weekly show pits celebrities with their real-life and TV families against each other.

They are all playing for charity.

The families include:

It's been a banner year for "Days of Our Lives" actor Thaao Penghlis.

This past spring, he earned his first Daytime Emmy nomination. For almost two decades, off and on, he's played Tony DiMera, a thorn in the side of many Salem residents.

And the Australian-born actor, who has Greek parents, became an American citizen.

Christopher Knight, once the fresh-faced Peter on "The Brady Bunch," isn't so sure he's ready for "Celebrity Circus."

"Up front, it's not fun," he says of the training for the series (9 p.m. EDT Wednesdays, NBC). "It's not fun when you're not confident.

Don't get Big & Rich front man John Rich started on the subject of "American Idol." He might blow a fuse.

The singer, who is a judge on "Nashville Star" this season as it moves from the USA Network to NBC, isn't much of a fan of "Idol." He lets you know it soon enough.

Yes, Sherri Shepherd knows the world is round.

Unfortunately, she said she wasn't so sure of its shape when asked about it a year ago on "The View." And her confusion on the subject brought her the kind of attention -- and public humiliation -- she didn't want the second day on the job.

"This tells you how exciting my career is," deadpans comedian Brian Regan. "I'm calling you from my basement."

Well, it's actually his office, which is in the basement of his house in Las Vegas. But he's not deterred by his location. "I do come up from my basement occasionally."
