The Iceman Ducketh is a 1964 Warner Bros. Looney Tunes theatrical cartoon directed by Phil Monroe and Maurice Noble, with a story by John Dunn. The short was released on May 16, 1964, and stars Bugs Bunny and Daffy Duck. It was the penultimate Warner Bros. theatrical cartoon to feature Bugs Bunny and the last Warner Bros. theatrical cartoon to feature Bugs and Daffy together until Cartoon All-Stars to the Rescue and the Looney Tunes Short, Box-Office Bunny in 1991, and the last that the Chuck Jones unit worked on, though Chuck Jones himself was fired at an early stage of production and replaced by Monroe. The title is a pun on Eugene O'Neill's 1946 theatrical play The Iceman Cometh, which would later be adapted into a movie.
