Yankee Dood It is a Warner Brothers Looney Tunes theatrical cartoon short released in 1956 and directed by Friz Freleng and written by Warren Foster. Yankee Dood It was the last of three cartoons to be underwritten by the Alfred P. Sloan Foundation, which also underwrote By Word of Mouse and Heir-Conditioned; like the other two, they are all available on Looney Tunes Golden Collection: Volume 6, Disc 2. This cartoon is also one of the rare cartoons where Sylvester has no speaking lines (except for "Ah-ha!" and "Sufferin' Succotash"), and thus there is no voice actor credit. Daws Butler voiced the shoemaker, and Arthur Q. Bryan voiced Elmer Fudd.
