Officially titled "Ringo," this show is sometimes called the "Ognir Rrats" special, since it featured the former Fab playing a character by that odd name (his own moniker spelled backwards), as well as himself.

Guests included Ringo's old pal George Harrison along with John Ritter, Angie Dickinson, Mike Douglas, Art Carney, Carrie Fisher and Vincent Price.
