Kildare, the Weirdest Duck in the World (titled Sgrizzo il Più Balzano Papero del Mondo in the original Italian) is a comic story written and penciled by Romano Scarpa and inked by Giorgio Cavazzano. It features Donald Duck, Huey, Dewey and Louie Duck and, in his debut, Kildare Coot.
Donald Duck's completely crazy cousin Kildare sneaks out of his psychiatric clinic and pays his relatives a visit. This would be all fine and good, if not for Donald Duck's new job, which requires peace and calm that is very opposite of the results of having hyperactive Kildare in the room.
