Elmer J. Fudd is a fictional cartoon character, one of the most famous Looney Tunes characters, and the tertiary
archenemy of Bugs Bunny. He has one of the most disputed origins in the Warner Bros. cartoon pantheon (second only to Bugs himself). His aim is to hunt Bugs, but he usually ends up seriously injuring himself and/or other antagonizing characters. He speaks in an unusual way (rhotacism), replacing his Rs and Ls with Ws, so "Watch da road, Rabbit," is replaced with "Watch the woad, wabbit!" Elmer's signature catchphrase is, "Be vewy vewy quiet, I'm hunting wabbits", as well as his trademark gloat, "huh-uh-uh-uh-uh-uh-uh-uh." The best known Elmer J. Fudd cartoons include Chuck Jones' masterpiece 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 himself, Bugs Bunny, and Daffy Duck. He is also a billionaire, who lives in a mansion and owns a yacht
- According to the Looney Tunes fans, there are various songs where the lead singer vaguely sounds like Elmer including "Let's Dance" by David Bowie, "Sweating Bullets" by Megadeth, and "Someday" by Sugar Ray.
- In 2000, Mark V. McCollum had recorded the song called "Kill The Wabbit" (which is apparently based on the Looney Tunes short "What's Opera, Doc?") and named Elmer being the lead singer as Ozzy Fudd. Live at the Comedy Tonight club in San Francisco 1992 (which is from the VHS tape), Mark is seen on the stage asking the audience "Speaking of dudes, what would it be like if Elmer Fudd had a punk sun? And his punk sun was into heavy metal and Ozzy Fudd had a hit video on MTV. Did you ever think what there would be like? I have." and performing the song as he portrays the voice impression of Elmer. While it is currently unknown whatever happened to Mark V. McCollum, the song is often credited to other bands such as Metallica and Megadeth.
