Stephen Tamill is a 5th Grade boy who appeared briefly in the Season Fifteen episode, "1%".
Upset with The 4th Grade class at South Park Elementary throwing off the results of the Presidential Fitness Test, Stephen and his friends protest the 99%. They believe it is unfair for the rest of the school to have to give up their recess because of Eric Cartman's lack of fitness.
Stephen wears black shoes, blue jeans, and a gray shirt with red sleeves. He has short brown hair.
