I am not one for celebrity roasts, but I am looking forward to this Comedy Central skewering of Charlie Sheen.

Since his character was killed off on the hit television series “Two and a Half Men,” Sheen has been making himself roastworthy.

Enjoy this clip of the Sept. 19 show, featuring “Family Guy” creator Seth MacFarlane:

What happened? Apparently, Microsoft (MSFT) realized that “Family Guy” is a ribald, off-color sitcom–but only after showing up to the taping of “Family Guy Presents: Seth and Alex’s Almost Live Comedy Show.”

Variety says “Family Guy” creator Seth MacFarlane and actor Alex Borstein did indeed promote Windows 7 during the Oct. 16 taping. Alas, “for most of the special, however, MacFarlane and Borstein made typical “Family Guy” style jokes, including riffs on deaf people, the Holocaust, feminine hygiene and incest.”

Whoda thunk?

Give Microsoft credit, though: At least the company figured this one out before the show actually aired–unlike the vomit ads it used to push Internet Explorer 8 last year. And, in defense of MacFarlane and Borstein, Google (GOOG) hasn’t seemed to run into any problems with the pact it struck with MacFarlane last year.

Microsoft’s backpedal, via Variety:

“We initially chose to participate in the Seth and Alex variety show based on the audience composition and creative humor of ‘Family Guy,’ but after reviewing an early version of the variety show it became clear that the content was not a fit with the Windows brand,” said a Microsoft spokesperson. “We continue to have a good partnership with Fox, Seth MacFarlane and Alex Borstein and are working with them in other areas. We continue to believe in the value of brand integrations and partnerships between brands, media companies and talent.”

Here’s a representative sample of the show Microsoft was betting on: A clip that Hulu says is one of its users’ favorites. Warning! The following includes flatulence, some sex talk and some racial stereotyping. No mention of Microsoft products, though.

This time it’s going to be different. That’s because Microsoft (MSFT) is paying to make it so. The company has teamed up with Fox to sponsor a “Family Guy” special built around Windows 7. The show, dubbed “Family Guy Presents: Seth & Alex’s Almost Live Comedy Show,” after creator Seth MacFarlane and voice talent Alex Borstein, will air Sunday, Nov. 8, at 8:30 pm, EST and PST.

The new episode will be free of commercial breaks but presumably rife with “clever” references to Windows. Microsoft agencies Universal McCann and Crispin, Porter and Bogusky, which were tapped to weave the company’s marketing messages into the program, will make sure of that.

“You’ll see us deeply integrated into the content,” Gayle Troberman, general manager of consumer engagement and advertising at Microsoft, told Ad Age. “You’ll hear a lot about how Windows 7 can help you simplify your PC–it’s simple, fast and easy to use.”

Sounds…hysterical.

Incidentally, it’s worth noting that this isn’t the first time MacFarlane has inked an advertising deal with a tech company. He’s currently working with Google (GOOG) on a project called “Seth MacFarlane’s Cavalcade of Cartoon Comedy,” which involves humorous animated shorts with built-in advertisements syndicated through the search giant’s AdSense advertising system.
