Flywheel, Shyster, and Flywheel

Flywheel, Shyster, and Flywheel is a situation comedy radio show starring two of the Marx Brothers, Groucho and Chico, and written primarily by Nat Perrin and Arthur Sheekman. The series was originally broadcast in the United States on the National Broadcasting Company's Blue Network, beginning on November 28, 1932, and ending on May 22, 1933. Sponsored by the Standard Oil Companies of New Jersey, Pennsylvania and Louisiana and the Colonial Beacon Oil Company, it was the Monday night installment of the Five-Star Theater, an old-time radio variety series that offered a different program each weeknight. Episodes were broadcast live from NBC's WJZ station in New York City and later from a sound stage at RKO Pictures in Los Angeles, California, before returning to WJZ for the final episodes.

The program depicts the misadventures of a small New York law firm, with Groucho as attorney Waldorf T. Flywheel (a crooked lawyer) and Chico as Flywheel's assistant, Emmanuel Ravelli (a half-wit whom Flywheel uses as a fall guy). The series was originally titled Beagle, Shyster, and Beagle, with Groucho's character named Waldorf T. Beagle, until a real lawyer from New York named Beagle contacted NBC and threatened to file a lawsuit unless the name was dropped. Many of the episodes' plots were partly or largely based upon Marx Brothers films.

The show garnered respectable ratings for its early evening time slot, although a second season was not produced. It was thought that, like most radio shows of the time, the episodes had not been recorded. The episodes were thought entirely lost until 1988, when 25 of the 26 scripts were rediscovered in the Library of Congress storage and republished. Adaptations of the recovered scripts were performed and broadcast in the UK, on BBC Radio 4, between 1990 and 1993. In 1996, some recordings of the original show were discovered (all recorded from the final three episodes), including a complete recording of the last episode to air.
