Robbie Rist

A towheaded, round-faced, sometimes bespectacled child performer who grew up to front a 1990s punk rock band, Robbie Rist appeared in over 100 TV shows as a child. He is perhaps best-recalled for his recurring roles as Cousin Oliver on ABC's "The Brady Bunch" and as the adopted son of Ted Baxter on "The Mary Tyler Moore Show." Rist had a featured role as a neighbor on the NBC drama "Lucas Tanner" (1974-75) and co-starred with Herb Edelman in the children's series "Big John, Little John" (NBC, 1976-77). By the 1980s, he was provided voices for characters in animated programs as well as developing a singing career. Rist can be heard as the voice of Michelangelo in "Teenage Mutant Ninja Turtles" (1990) and its two sequels. After working with several garage bands, he found his widest audience as a musician with the 90s punk band Wonderboy.
