Frank Brandon Nelson (May 6, 1911 – September 12, 1986) was an American comedic actor best known for playing put-upon foils on radio and television, and especially for his "EEE-Yeeeeeeeeesssss?" catchphrase. He made numerous guest appearances on television shows, including The Jack Benny Program, I Love Lucy, The Real McCoys, The Addams Family, Alice, and Sanford and Son. He also provided voices for animated series such as The Flintstones, Mister Magoo, The Jetsons, Dinky Dog, and The Snorks. Career Radio Nelson began his entertainment career in radio, and later moved into television and movies. In 1926, at age 15, Nelson played the role of a 30-year-old man in a series broadcast from KOA in Denver, Colorado. In 1929, Nelson moved to Hollywood, California, and worked in local dramatic broadcasts, usually playing the leading man. The first sponsored program in which he appeared that reached a national market was Flywheel, Shyster, and Flywheel, a situation comedy that aired from November 28, 1932, to May 22, 1933, starring Groucho and Chico Marx, and written primarily by Nat Perrin and Arthur Sheekman.

Nelson, whose character was never given a name, typically portrayed a sales clerk, dentist or customer service worker, and Benny's character would run into him seemingly out of nowhere. For example, needing airline tickets, Benny would call the ticket agent, "Oh Mister? Mister?" Nelson would then deliver his catchphrase, a bellowed "EEE-Yeeeeeeeeesssss?" The two men would banter, with Nelson gleefully delivering insulting one-liners such as, "Is that a hairpiece or did someone plant moss on your head?", and sarcastic responses like, after being asked at an airport ticket counter if he was the ticket clerk, "No, I'm a 747 with a moustache." Whatever his occupation in a particular episode, Nelson's character would usually be polite and patient with all of his customers except for Jack Benny. An especially noteworthy example occurred on the episode that aired Jan. 8, 1950. Early in the show, announcer Don Wilson mispronounced columnist Drew Pearson's name as "Drear Pooson," which got a big laugh. The writers made a quick change to the script, and later, when Benny
