- "OH MY GOSH! THEY KILLED KENNY!"
- ―Stan whenever Kenny dies
Stan Marsh is one of the main characters of South Park. he is known for being the only South Park character, aside from Chef, who could actually be considered normal (Kyle is a supergenius, Cartman is a modern day Archie Bunker, and Kenny literally can't die).
Stan's personality is largely based on Trey Parker (who also voices him), but there are several differences. Like his grandfather, Stan gets addicted extremely easily, his latest addiction being the freemium game Terrance and Phillip: Give Us Your Money! (an extremely stupid game that the infamous Canadians didn't aprove).
- Stan is the only main character who hasn't explored his feminine side (Cartman has a female alternate personality, Kyle has a female World of Warcraft avatar, and Kenny, due to losing a bet, dressed up like a princess in a Game of Thrones parody).
- Stan has asthma.
- As a running gag in the early years, Stan would loose his lunch whenever he got nervous, usually happening when Wendy talks to him. He has since gotten over this.
- Stan is the only one who doesn't have a "HOLY COW! THEY KILLED" line about him.
