Some meanings of a pinkie ring:
"Wearing a ring on the little, or pinky, finger of the hand can have any one of a number of meanings, some of which are mutually contradictory. It may also have no other significance at all beyond the personal preference of the wearer.
Homosexuality
In the 1950s through the 1970s, wearing a pinky ring was sometimes used as a covert sign of male homosexuality. Judy Grahn in her book "Another Mother Tongue" writes that in 1959, the year she came out, that rings worn on the pinky were known as a secret way to communicate homosexuality.
Engineers
American and Canadian engineers sometimes wear a steel or iron ring to signify oath-bound membership in an engineering fellowship.
Signet Rings and Aristocracy
The signet ring, a type of ring bearing a family crest and used to seal letters and mark other documents, was traditionally worn on the little finger. As a result, rings worn on the little finger became associated with aristocracy in general.
Organized Crime
Members of organized crime are reputed to wear pinky rings as well. In more recent times, hip-hop artists with a "gangsta" style adopted pinky rings in imitation of their Italian-American counterparts.
Luck
Some people believe that wearing a pinky ring can bring the wearer luck. Gamblers, in particular, are prone to sporting one."

My personal belief is that Letts pinkie ring is an old secret decoder ring he got in a Kracker Jack Box
when he was 7 years old. He believes it explains the scriptures to him.
Jehovah put him in his position to test his people.
Out of courtesy to him they shouldn't have a guy like that anywhere near a microphone. It is like poking fun of a hunchback.
