The South Parkers are the latest pop culture icons to grace the tees,which in the past have featured Naomi Campbell, Dita von Teese and Victoria Beckham.

Getting Butters to bare all, however, proved more difficult than Jacobs and company president Robert Duffy anticipated. “They’re very, very cautious about collaborations,” Duffy said of Parker and  Stone. “We’ve worked with so many artists in the past, and I’d say Trey and Matt are the most protective of their brand. They were so involved, to the point of wanting to know the texture of the T-shirt and how thick the paint is on the silk screen.”

And sadly Duffy’s dream of disrobing a particular character were inevitably dashed: “I really wanted to do Kenny, but they said there was absolutely no way they were going to let me use Kenny. I wanted to see what he looks like without his coat.”

The T-shirts retail for $35 and are available online and at Marc by Marc Jacobs stores. [WWD]

This makes me laugh every time.I think one thing that will never get old about South Park is how blatently offensive they are, but they’re allowed to be because they make sure it is spread around to everyone haha!
