"I'm the Greatest" (1973)
Lennon, who wrote this song, realized that the boastful lyric would make him sound like a jerk (again). Ringo, however, could pull off its ironic swagger by resurrecting his Sgt. Pepper's alter ego, Billy Shears. It's the only recording featuring all four members of the mythical post-Beatles group the Ladders, which was rumored to include John, George and Ringo, with artist Klaus Voorman taking Paul's place on bass.
