"I'm not fat, I'm just big boned!"-Cartman, South Park 

Now fashionistas can judge this claim for themselves with Marc Jacobs' new T-shirts featuring a naked Cartman along with his fellow South Park residents Randy Marsh and Butters Stotch.  The trio pose protecting their manly bits behind the the slogan "Protect Your Largest Organ." 

We love that Marc Jacobs paid it back to the South Park dudes after they featured him on an episode as Cartman's doll, "Muscle Man Marc."  These shirts are the latest version of Jacobs' and Marc Jacobs president Robert Duffy's collaboration with the Interdisciplinary Melanoma Cooperative Group at New York University, wherein proceeds from the items' sales benefit the non-profit.  You can snag one for $35 online or at any Marc by Marc Jacobs boutique.

If only we could glimpse Anna Wintour or Carine Roitfeld in one of these tees during fashion week...but that's just wishful thinking.
