Big John, Little John

I remember watching Herb Edelman's character Big John,become a little boy every episode.I was just 5 years old and thought how great it could be an adult,now over 23 years later I now think different.Look for Robbie Rist as Little John,Rist played on "The Brady Brady bunch" as cousin Oliver for one season then vanishes with no explanation,we now know the truth. Ole Sherwood Schwartz creator of "The Brady Bunch" and "Gilligan's Isand" also created "Big John,Little John"
