In a recent episode of South Park, Marc Jacobs appeared as one of Cartman's dolls.
Marc Jacobs was a special guest star on Wednesday night's episode of "South Park," appearing as one of Cartman's toys called "Muscle Man Marc."
In the episode, Muscle Man Marc first makes an appearance at a tea party with Cartman and his other toys. Later, when something happens to Cartman's toy, Clyde Frog, the character confronts Cartman's mother over more tea. (For any more details, you'll just have to watch the episode.)
In an interesting twist, The Cut blog points out that Marc Jacobs actually has a tattoo of Clyde Frog on his right arm.
