Stough was born in Evergreen, Colorado, and has characterized his upbringing as "well-rounded, sheltered and I did what I was told." He met Trey Parker at age 13; the two later acted in school musicals and made short films together at Evergreen High School. Stough grew up interested in animation and aspired to be a "great Disney animator", but was not the best at drawing. He attended the University of Colorado at Boulder, where he initially studied in their art department. Parker convinced him to instead join their film department, as he would be able to make animated films rather than spend his time perfecting his drawing. He had an internship with Jim Henson Productions in college. He graduated with a film degree in 1995, and subsequently worked with Parker and Matt Stone on the short filmThe Spirit of Christmas. The film grew popular and resulted in a television deal with Comedy Central to produce an animated series based on it, which became South Park. Stough was the first crew member hired on South Park, which premiered in 1997, and remains the show's producer and animation director to this day. He has also worked on various South Park-related projects, including the show's and the video game', as well as Orgazmo, ' and the Broadway hit The Book of Mormon, which he illustrated for. The character of Butters in South Park is based on Stough and his sheltered upbringing. He noted in his commencement address for UCB in 2014, "The nickname "Butters" stems from little brother, little buddy and innocent wholesome person." Stough has also provided the un-muffled voice of Kenny McCormick in four episodes of the show, "The Jeffersons," "Lice Capades," "Mysterion Rises" and "Turd Burglars". He did not however provide the main voice of Kenny's alter-ego Mysterion. Stough married in 2011 and has two children ages 2 and 7. He abruptly filed for divorce in April 2020.
