The Life of Riley is an American radio situation comedy series of the 1940s that was adapted into a 1949 feature film, a 1950s television series, and a 1958 comic book.

Radio:

The radio program initially aired on the Blue Network (later known as ABC) from January 16, 1944, to July 8, 1945, it then moved to NBC, where it was broadcast from September 8, 1945, to June 29, 1951.

Irving Brecher pitched the radio series for friend Groucho Marx under the title The Flotsam Family, but the sponsor balked at what would have been essentially a straight head-of-household role for Marx. (Marx would get his own series Blue Ribbon Town instead.) Brecher then saw William Bendix as taxicab company owner Tim McGuerin in Hal Roach's The McGuerins from Brooklyn (1942). Radio historian Gerald Nachman quotes Brecher as stating, "He was a Brooklyn guy and there was something about him. I thought this guy could play it. He'd made a few films, like Lifeboat, but he was not a name. So, I took The Flotsam Family script, revised it, made it a Brooklyn Family, took out the flip-flippancies and made more meat-and-potatoes, and thought of a new title, The Life of Riley. Bendix's delivery and the spin he put on his lines made it work."

The reworked script cast Bendix as blundering Chester A. Riley, a wing riveter at the fictional Cunningham Aircraft plant in California. His frequent exclamation of indignation—"What a revoltin' development this is!"—became one of the most famous catchphrases of the 1940s. It was later reused by Benjamin J. Grimm of the Fantastic Four. The radio series also benefited from the immense popularity of a supporting character, Digby "Digger" O'Dell (John Brown), "the friendly undertaker." Brecher told Brown, "I want a very sepulchral voice, quavering, morbid," and he got it right away.

The supporting cast featured Paula Winslowe as Riley's wife, Peg, and as Riley's mother-in law; Brown as O'Dell and as Riley's co-worker Jim Gillis; Francis "Dink" Trout as Waldo Binny; Tommy Cook, Bobby Ellis and Scotty Beckett as Junior at various times during the show's run; Barbara Eiler as Riley's daughter, Babs; Shirley Mitchell as Honeybee Gillis; Hans Conried as Uncle Baxter; and, Alan Reed as multiple characters, including Riley's boss (Mr. Stevenson) and Peg's father. Henry Morgan voiced Riley's father in one episode. Mel Blanc provided some voices as well, including that of Junior's dog Tiger as well as that of a dog catcher who claimed to have a special bond with dogs.

Mitchell's Gillis often gave Riley bad information that got him into trouble, whereas Brown's Digger gave him good information that "helped him out of a hole," as he might have put it. Brown's lines as the undertaker were often repetitive, including puns based on his profession; but thanks to Brown's delivery, the audience loved him. The program was broadcast live with a studio audience, most of whom were not aware Brown played both characters. As a result, when Digger delivered his first line, it was usually greeted with howls of laughter and applause from surprised audience members.

The series was co-developed by the non performing Marx Brother turned agent Gummo. The American Meat Institute (1944–45), Procter & Gamble (Teel dentifrice and Prell shampoo) (1945–49), and Pabst Blue Ribbon beer (1949–51) took turns as the radio program's sponsor.

An unrelated radio show with the title Life of Riley was a summer replacement show heard on CBS from April 12, 1941, to September 6, 1941. The CBS program starred Lionel Stander as J. Riley Farnsworth and had no real connection with the more famous series that followed a few years later.
