Stanely "Stan" Marsh is one of the four main characters of South Park. Stan, who is simply a kind, honest kid, generally serves as one of the shows main protagonists, a role generally shared with Kyle. They usually, of course, go up against Cartman. During the initial seasons, Stan's catch phrase used to be "Oh my God, they killed Kenny!" shortly after Kenny died. He was also pretty well known for always vomiting on his girlfriend Wendy. Now, he just mostly goes on crazy adventures.
Kyle: Dude, I have to save Ike! I don't even know what to do!
Stan: Well, we can't do anything now; that fat bitch won't let us!
Ms. Crabtree: WHAT DID YOU SAY?!?
Stan: I said that rabbits eat lettuce.
Ms. Crabtree: Oh. Well, yes, they certainly do...
Stan: What's gonna be for lunch today Chef?
Chef: Well, today it's Salisbury steak with buttered noodles, and a choice of green bean casserole, or vegetable medley.
