First and only episode Steve Austin does a back somersault.
This Olympic themed episode was due to ABC telecasting the Winter 1976 Olympics (which had just finished when this first aired). In addition, Cathy Rigby had become a household name after her performance at the 1968 Olympics (just as Peggy Fleming had at that year's Winter Olympics). Rigby playing a Russian gymnast was also a way to promote ABC's upcoming telecast of the Summer Olympics.
