The voices of Kelly Generic (Bobby's sister) and Martha Generic (Bobby's mom) are based on two characters Gail Matthius played when she was a member on "Saturday Night Live" in 1980. Martha is based on the character Roweena, a chain smoking hair stylist with a Upper Midwestern accent who gets into arguments with her best customer Nadine (Denny Dillon), while Kelly Generic is based on the character Vicky, a valley girl who annoys others with her shallow questions and rambling stories and often is seen with her friend Debbie (also Dillon).
