Hot-blooded hotel heiress Paris Hilton (search) is making an unauthorized stop in "South Park" (search) this week.

On the Comedy Central show, the girls of South Park's fourth grade idolize Hilton, and each one owns Paris' "very special toy set" -- a kit that comes complete with video camera, night-vision filter, play money and losable cell phone.

When word reaches the girls that Paris might visit South Park, they try to impress their idol by getting the town's boys to help make their own "videos"

The real Hilton -- who made waves last year when a pornographic video of her surfaced on the Internet -- did not participate in the making of the "South Park" episode.
