On a "Trading Spouses"-type show, Homer is forced to take in a controlling wife, while Marge moves in with a beaten-down husband, Charlie (guest star Ricky Gervais), and his perfect son.

Over the past two decades, "The Simpsons" has been about a nuclear family — Homer, Marge and their three kids. But it has also had a lineup of guest stars unrivaled in television history.

Oscar winners. Emmy winners. Grammy winners. Tony winners. Pulitzer Prize winners. Nobel Prize winners.

Astronauts. Billionaires. Sportscasters. Comedians.

Super Bowl-winning quarterbacks. Hall of Fame baseball players. Wimbledon winners. A Tour de France champion.

Three of the four Beatles. Even a British prime minister.
