Award Snub: John Lennon, Paul McCartney, and George Harrison were all inducted into the Rock and Roll Hall of Fame for their solo careers in 1994, 1999, and 2004 respectively, in addition to The Beatles being inducted as a group in 1988. Ringo as a solo artist was not inducted for a long time, finally being awarded in 2015. Although even there, he was given the "Award for Musical Excellence," which is generally given to side men.
Awesome Music: Ringo believes the drumming he did on the Beatles song "Rain" is the best he ever recorded, and it's hard to disagree with him (though his work on "She Said, She Said" and "A Day in the Life" stands out as well).
Musicologists and musicians tend to agree that Ringo was a good drummer, on the grounds of his mastery of subtle things like tempo and timbre control; he was constantly retuning and messing with his kit in order to get different sounds out of it, he always tailored his part for each song, and while drummers in popular culture are expected to be Crazy Awesome, Ringo disliked showing off. He only has one drum solo in the entire Beatles discography, on "The End", and even then he had to be persuaded to take it. The reason why the general public isn't unanimously agreed that he was a good drummer is that these are not the kind of drumming skills that impress non-musicians.
Memetic Mutation: His infamous video in which he announces no more fan mail has done the rounds as a copypasta, as as inferring "I'm warning you with peace and love" as an Implied Death Threat.
Unpopular Popular Character: Many fans adore him simply because he's not as mainstream as John and Paul, though he has his share of detractors. Other fans love him because he's easily the most humble and approachable of the group. John, Paul, and even George are these epic gods of rock, while Ringo is the sort of guy you'd like to hang out and have a beer with.
