Big John, Little John is an American Saturday-morning situation comedy, produced by Sherwood Schwartz, which starred Herbert Edelman as "Big John" and Robert "Robbie" Rist as "Little John."

In the United Kingdom, it was shown on BBC One.

Plot summary

Little John (Robbie Rist), as seen in the opening credits.

The show's main character was a forty-year-old middle school science teacher named John Martin (played by Edelman). While vacationing in Florida, he drinks from a spring which turns out to be the legendary Fountain of Youth sought by Juan Ponce de León. The water changes him into a twelve-year-old boy (played by Rist), and back again.

The changes occur spontaneously and without warning. Because Martin only sipped the water, the changes are recurring and not permanent; according to legend, had he taken a full drink, he would be age twelve permanently. Only his wife, Marjorie (Joyce Bulifant), and son, Ricky (Mike Darnell), know his secret, though Martin's students (who befriend him as "Little John") and his boss, principal Bertha Bottomly (Olive Dunbar), do become suspicious that something unusual is going on. The Martin family explain the younger John as their nephew, staying with them. Throughout the series, "Big John" unsuccessfully tries to find a cure for his predicament, but his experiences as "Little John" often give him insight into what his students are facing.

To make the two actors resemble each other more closely, Rist's blond hair was dyed brown, while Edelman wore a hairpiece that partially covered his baldness, though was absent during the credits sequences. Edelman and Rist appeared together in 1977, on the Jerry Lewis MDA Telethon.
