Muntz was a friend of Steve Sanders, who he originally met as part of the KEG fraternity. Largely used as comic relief, Muntz was usually seen languishing in the background at parties getting drunk or dispensing boos himself. He was largely loyal to Steve and was one of the first brothers to blackball John Sears when the vote came to banish one or the other from their fraternity. He was virgin until Steve lent him Andrea Zuckerman's dorm room to use with his girlfriend, Sherry.
As the series went on, he usually showed up at special events, such as birthday parties, graduations, and weddings, eventually getting married himself to Julie Muntz. Muntz was in attendance to Donna and David's wedding in the series finale.
