Mickey Mouse's global fame has made him both a symbol of The Walt Disney Company and of the United States itself. For this reason, Mickey has been used frequently in anti-American satire, such as the infamous underground cartoon ""Mickey Mouse in Vietnam"" (1969). There have been numerous parodies of Mickey Mouse, such as the two-page parody ""Mickey Rodent"" by Will Elder (published in "Mad" #19, 1955) in which the mouse walks around unshaven and jails Donald Duck out of jealousy over the duck's larger popularity. The grotesque Rat Fink character was created by Ed "Big Daddy" Roth over his hatred of Mickey Mouse. In "The Simpsons Movie", Bart Simpson puts a black bra on his head to mimic Mickey Mouse and says: "I'm the mascot of an evil corporation!" On the Comedy Central series "South Park", Mickey is depicted as the sadistic, greedy, foul-mouthed boss of The Walt Disney Company, only interested in money. He also appears briefly with Donald Duck in the comic "Squeak the Mouse" by the Italian cartoonist Massimo Mattioli. Horst Rosenthal created a comic book, "Mickey au Camp de Gurs" ("Mickey Mouse in the Gurs Internment Camp") while detained in the Gurs internment camp during the Second World War; he added "Publié Sans Autorisation de Walt Disney" ("Published without Walt Disney's Permission") to the front cover.
