Elmer J. Fudd is an animated cartoon character in the Warner Bros. Looney Tunes/Merrie Melodies series and the archenemy of Bugs Bunny. Elmer's aim is to hunt Bugs, but he usually ends up seriously injuring himself and other antagonizing characters. He exhibits the speech sound disorder known as rhotacism, replacing his Rs and Ls with Ws thus referring to Bugs Bunny as a "scwewy" (screwy) or "wascawwy (rascally) wabbit." Elmer's signature catchphrase is, "Shhh. Be vewy, vewy quiet, I'm hunting wabbits", as well as his trademark laugh. The best known Elmer Fudd cartoons include Chuck Jones' work What's Opera, Doc?, the Rossini parody Rabbit of Seville, and the "Hunting Trilogy" of "Rabbit Season/Duck Season" shorts (Rabbit Fire, Rabbit Seasoning, and Duck! Rabbit, Duck!) with Elmer Fudd, Bugs Bunny, and Daffy Duck. An earlier prototype of the character named Egghead had some of Elmer's recognizable aspects before the character's more conspicuous features were set.
