Ricky Gervais and Will Arnett are guest starring on the season 7 finale of 'The Office.' Take a moment and soak that in.

According to Entertainment Weekly, the episode is still being written so the roles are still taking shape.

Earlier this season Gervais reprised his role of David Brent from the UK version of 'The Office' and made a brief cameo opposite Steve Carell's Michael Scott. EW's source warned that viewers shouldn't assume Gervais or Arnett will play the new boss of Dunder Mifflin.

Last week, 'Dancing With the Stars' producers weren't sure if they could get the rights to 'The Brady Bunch' theme song for Florence Henderson (aka Carol Brady) and pro partner Corky Ballas to use during their TV theme week performance.

As viewers saw last night, the song was approved. While it wasn't perhaps the best tune to tango to, it did have great sentimental value to Henderson.

"The reason I really wanted to dance to the 'Brady Bunch' theme was because I wanted to dedicate it to Bob," Henderson told TV Squad on the post-show press line, referring to the late Robert Reed (who played her TV husband Mike Brady.)

"To lose him to AIDS [in 1992] broke all of our hearts. The fact that Barry [Williams, Greg] was here and knows how close we all were to Bob ... that was my dedication tonight."

There are six human beings on this planet who will be forever linked by one experience: growing up on the set of The Brady Bunch. But, of the six actors who played the Brady kids during the show's 1969-74 run, none has embraced the role as consistently and enthusiastically as Barry Williams, who played Greg. Over the years, Williams has been involved in every reunion show (including the ill-fated "dramatic" show The Bradys in 1990) and has never shied away from discussing the show during interviews. He even wrote a book about the experience, 1992's Growing Up Brady: I Was a Teenage Greg, where he recounted stories like his crush on co-star Maureen McCormick, his "date" with his TV mom, Florence Henderson, and Robert Reed's constant arguments with the producers. The book was made into a TV movie in 2000.

Now, at 53, Williams has a blog, called The Greg Brady Project, which debuted in December. There, Williams tells stories about his experiences as an actor over the last 40-plus years while a series of co-writers wax nostalgic about the past, and not necessarily about The Brady Bunch. I spoke to Williams by phone earlier this month. We talked about the blog, why he's embraced his Greg Brady past more than his co-stars, and what he thinks of some of those co-stars' new projects. The interview is after the jump.

If you've read any of the 200 books written about The Brady Bunch or seen any of the TV movies or "behind the scenes" exposes, you know that Robert Reed wasn't a big fan of the show's scripts. In fact, he had battles with the producers on the show many times and even refused to be in a couple of episodes because of the plot and/or his arguments with the people in charge of the show.

And it wasn't just verbal arguments. Reed actually took the time to send memos to the producers explaining why a certain plot point/line/scene didn't make sense. Reed was a veteran TV (The Defenders) and stage actor and often referred to Shakespeare in his memos. This site has one of the memos, and after the jump is the full text of the memo (it's about the classic episode where Greg's hair turns green because of some shampoo Bobby sold him).

Yeah, that headline doesn't sound quite right does it? To quote George Constanza, "Worlds are colliding!"

Gilligan's Island: The Musical is a stage play that brings the TV classic to the theater. They'll be performing the show at the Coral Springs Center For The Arts in Coral Springs, FL, February 2-11. The role of millionaire Thurston Howell III will be played by Barry Williams, who played Greg Brady on The Brady Bunch, another Sherwood Schwartz show. And to make matters even more confusing, Dawn Wells, who played Mary Ann on Gilligan's Island, will not reprise her role. Instead, she'll play Mrs. Howell!

This just isn't right. What if they mix up the theme songs? "Just sit right back and you'll hear a tale...here's the story! Of a man named Skipper!"

They should have other classic TV stars play the other roles. How about Ann B. Davis as Ginger?

Some activities aren't hindered too much by a little pot smoking, such as performing dental surgery or piloting commercial aircraft. Trying to act on a popular sitcom when you're stoned, however? Well, that's just plain dangerous. Barry Williams, in his autobiography I Was a Teenage Greg, recalls a scene he did for the Brady Bunch during which he was extremely high. It's subtle, and if I didn't actually know he was high I don't know if I would have noticed anything that odd about his performance, but Destiny-land has some excerpts from Williams' book where he writes about making up dialogue, doing some of his own improvisations, and developing some kind of Zen connection with his bicycle. He does seem a little out of it, and watch how he trips over his bike pump as he walks over to the car. The video is after the jump:

No, the other guy. The middle kid. Christopher Knight, who played Peter Brady on The Brady Bunch television series and now has his own reality show on VH1, got married over the holiday weekend to another reality television star. Knight, 47, met Adrianne Curry, 23, when they were both on The Surreal Life. They went on to star in the reality series, My Fair Brady, and in the sequel, My Fair Brady: We're Getting Married. The actual wedding was May 29th and some of Knight's former co-stars attended, including Barry Williams (Greg Brady), Susan Olsen (Cindy Brady), and Mike Lookinland (Bobby Brady). There's no official air date for the nuptials.

After all these reality shows, when do you think reality will actually set in for these two lovebirds?

I think I can say, without fear of contradiction, that all of us who grew up with the Brady Bunch wanted just once to see Greg and Peter making out. According to Herbie JP over at Media Village TV Monitor, actors Barry Williams (Greg) and Christopher Knight (Peter) will share a kiss on an upcoming episode of That 70s Show. The episode is set to air on April 27 and is titled "Josh and Jeff." All I can say is the kiss better be convincing. I won't accept anything less than a sweaty, groping, open-mouthed kiss that lasts for twelve straight minutes. Otherwise, I'm tuning out.
