* AccidentalInnuendo: "My spear and magic helmet!"
* AwardSnub: The 2002 CartoonNetwork special ''The 1st Ever 13th Annual Fancy Anvil Awards Show Program Special (Live in Stereo)'' featured ''What's Opera, Doc?'' as one of the nominees for the Best Cartoon award. Unfortunately, it lost to the ''WesternAnimation/DextersLaboratory'' episode "Mock 5".
** And of course the short was not nominated for an Academy Award.
* SugarWiki/AwesomeMusic: "Ride of the Valkyries" by Wagner.
* EarWorm: "Kill da Wabbit! Kill da Wabbit! Kill da WABB-it!" Why that's not a meme yet is beyond me.
** Because people were more interested in Elmer's spear and magic helmet as memeage.
* HypeBacklash: Bound to get a bit of this since it's considered the greatest cartoon short of all time by several historians.
* MemeticMutation: ''With my speaw and Magic '''HEW-MEEEETTTT!'''''
** "Your spear and magic helmet?"
* SugarWiki/MomentOfAwesome: Elmer Fudd, Looney Tunes' biggest resident ButtMonkey and IneffectualSympatheticVillain, finally gets one.
* NightmareFuel: For anyone who had the misfortune of seeing this when they were too young. You're expecting a normal, happy cartoon, and then Elmer Fudd SUMMONS A STORM THAT [[spoiler: SEEMINGLY]] KILLS BUGS BUNNY!
** The beginning of this cartoon seems like a ShoutOut to the Night on Bald Mountain sequence from {{Disney/Fantasia}}.
* TearJerker: If an unintentional one, not unlike Chuck Jones' ''FeedTheKitty.''
** Lampshaded in the BreakingTheFourthWall line cited on the main page.
* WeirdAlEffect: This short is arguably the source of many a modern person's knowledge of all things Wagner, to the point where some people don't even know the short was actually based on a real opera.
