"Homer's Barbershop Quartet"
Season 5, Episode 12

In a take-off on the Beatles' final public performance, the Be Sharps reunite on top of Moe's Tavern. Like the famous foursome, the barbershop quartet is decked out in stylish gear, with Home rocking the red peacoat originally donned by Ringo, and Barney in the fur number that John Lennon wore. A bittersweet moment, as the Be Sharps broke up immediately following this performance. But the guy who had the worst day was the Human Fly, who was up all night dying his underwear.
