Goofy is an animated cartoon character from the Walt Disney's Mickey Mouse universe. He is an anthropomorphic dog and is one of Mickey Mouse's best friends. His original concept name was "Dippy Dawg" in cartoon shorts created during the 1930s; then his name was given as "George Geef" or "G.G. Geef" in cartoon shorts during the 1950s, implying that "Goofy" was a nickname. In Goofy Gymnastics, he fills out a coupon with the name "James Boyd" (actually the name of a Disney staffer who worked on the cartoon). Some 1990s sources, including the Goof Troop television show and A Goofy Movie, gave the character's full name to be Goofy Goof; the Goof Troop pilot also refers to 'G. G. Goof' on a diploma, likely a reference to the 1950s name. In many other sources (both animated and comics), the surname Goof continues to be used; in other recent comics, the character's full name has been given as Goofus D. Dawg, a name that was used as early as 1957 in the "Great gawrsh-durn champion" by Romano Scarpo and possibly earlier.
