Elmer J. Fudd is an animated cartoon character in the Warner Bros. Looney Tunes/Merrie Melodies series and the archenemy of Bugs Bunny alongside Yosemite Sam. His aim is to hunt Bugs, but he usually ends up seriously injuring himself and other antagonizing characters. He speaks in an unusual way, replacing his Rs and Ls with Ws, so he often refers to Bugs Bunny as a "scwewy" or "wascawwy (rascally) wabbit". Elmer's signature catchphrase is, "Shhh. Be vewy vewy quiet, I'm hunting wabbits", as well as his trademark laughter. The best known Elmer Fudd cartoons include Chuck Jones' work What's Opera, Doc? (one of the few times Fudd bested Bugs, though he felt bad about it), 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 Fudd, Bugs Bunny, and Daffy Duck. An earlier prototype of character named Elmer set some of the recognizable Elmer's aspects before the character's more conspicuous features were set. Tex Avery introduced a new character in his cartoon short Egghead Rides Again, released July 17, 1937. Egghead initially was depicted as having a bulbous nose, a voice like Joe Penner (provided by radio mimic Danny Webb) and an egg-shaped head. Many cartoon historians believe that Egghead evolved into Elmer over a period of a couple of years. However, animation historian Michael Barrier asserts, that "Elmer Fudd was not a modified version of his fellow Warner Bros. character Egghead" and that "the two characters were always distinct. That was evidenced by Elmer's early prototype being identified in a Warner publicity sheet for Cinderella Meets Fella (filed with the Library of Congress as a copyright description) as 'Egghead's brother.'" and that "The Egghead-Elmer story is actually a little messy, my sense being that most of the people involved, whether they were making the films or publicizing them, not only had trouble telling the characters apart but had no idea why they should bother trying.
