The boys of Comedy Central's "South Park" (search) and the gals of HBO's "Sex and the City" (search ) will lose a bit of their mojo when moving from cable to over-the-air syndication in 2005.

Both shows, known for rough language and risque plotlines, have been scrubbed a little cleaner for their broadcast runs, according to Broadcasting & Cable magazine.

It's all part and parcel of the uproar since Janet Jackson's breast-baring Super Bowl (search ) appearance - which spurred a clampdown on broadcast standards.

"Clearly, people are clamping down," newly minted Comedy Central chief Doug Herzog told The Post yesterday. "Everybody is getting themselves a little more buttoned up.

"I'm sure we're doing that too . . . but the standards issues are things that we deal with every day."

B&C screened several episodes of "South Park" and "Sex and the City," episodes that syndicators are taking to local stations to prove the shows can work outside of cable's anything-goes atmosphere.

In a "South Park" episode that takes place in Afghanistan, Cartman says "God, what a craphole, dude! This is like East Denver! Jesus Chrrrrist!"

That was on Comedy Central. In the syndicated version, Cartman's line was changed to "God, what a craphole, dude! This is like East Denver!"

Not all terms that might be deemed offensive have been expunged from "South Park".

"It's hard to feel like we're going to take a step backward. I certainly hope not," says Herzog. "We're an adult network and we program it responsibly."

Mort Marcus, president of Debmar Studios, which is selling "South Park" in syndication, told B&C that about 15 percent of the show's 155 syndicated episodes are, most likely, too dirty to air.

It's much the same situation for "Sex and the City" Three episodes of "Sex," headed for syndication and screened by B&C, were left largely intact - except for having much less of Samantha (Kim Cattrall), who often engaged in racy behavior.
