The song's history began when Lennon was inspired by Timothy Leary's campaign for governor of California titled "Come together, join the party" against Ronald Reagan, which promptly ended when Leary was sent to prison for possession of marijuana.[5] It has been speculated that each verse refers cryptically to each of the Beatles (e.g. "he's one holy roller" allegedly refers to the spiritually inclined George Harrison; "he got monkey finger, he shoot Coca-Cola" to Ringo Starr, the funny Beatle; "he got Ono sideboard, he one spinal cracker" to Lennon himself; and "got to be good-looking 'cause he's so hard to see" to Paul McCartney); however, it has also been suggested that the song has only a single "pariah-like protagonist" and Lennon was "painting another sardonic self-portrait".[6]

Very interesting, never heard that. I know the first line of the song was lifted directly from You Can't Catch Me by Chuck Berry.
