Maypo is a brand of maple-flavored oatmeal. It was developed by the Maltex Corporation in Burlington, Vermont, in 1953. It was famous for its television commercials with the catchphrase, "I want my Maypo!" by Marky Maypo in 1956 by the Fletcher, Richards, Calkins & Holden Advertising Agency with the animation created by John Hubley.
Maypo's television ads sometimes featured athletes—including Mickey Mantle, Wilt Chamberlain and Johnny Unitas—crying "I want my Maypo!"
