South Park duo Trey Parker and Matt Stone have made plenty of headlines lately for their enduring quest to re-boot Casa Bonita near Denver, Colorado. However, their long-running animated satire continues to fire away at targets. And although it does so in an equal-opportunity way (no one is immune, including all nooks and crannies of the British Royal Family), one target from the past has taken particular offense and is now airing those concerns. That would be Paris Hilton, whose new memoir (aptly titled Paris: The Memoir) is a bit of a Festivus. She’s airing grievances, in other words, including about how Pink parodied her sex tape in the “Stupid Girls” video.
