The Toothpaste Millionaire --
November 27, 1974 (unavailable)
A boy within the age of the target demographic invents his own kind of toothpaste and becomes a successful businessman. Many of the really bizarre ones were missing, either because I didn't have that TV Guide issue, the affiliate didn't air the episode, or ABC didn't run an ad for it.
