* AccidentalInnuendo: "My spear and magic helmet!"
* AwardSnub: The 2002 Creator/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. (Warner Bros. instead nominated ''WesternAnimation/TabascoRoad'' and ''WesternAnimation/BirdsAnonymous'', the latter of which got the Oscar.)
* SugarWiki/AwesomeMusic: "Ride of the Valkyries" by Wagner.
** Silly as a rabbit in drag singing a love duet with a little bald man is, Mel Blanc and Arthur Q. Bryan's voices are still [[CrowningMusicOfAwesome actually pretty lovely]] during the "Return My Love" song.
* EarWorm: "Kill da Wabbit! Kill da Wabbit! Kill da WABB-it!"
* FoeYay[=/=]HoYay: The usual RunningGag in shorts; Bugs DisguisedInDrag, and Elmer falling head over heels for him. What's a little different here is that the "Return My Love" segment is pretty sappy, cliché and emotional yet still funny, while all other times Bugs pulled out his drag act it was only PlayedForLaughs.
* 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?"
** ''"Kill da Wabbit! Kill da Wabbit!"''
** "Well, what did you expect from an opera? A ''happy'' ending?"
* 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!
-->"Awise, stowm! Norf winds, blow! Souf winds, blow! Typhoons, hurricanes, earthquakes! '''[[BigWordShout SMMMMOOOOOOOOOGGGGGG!!!!]]'''"
** The beginning of this cartoon seems like a ShoutOut to the Night on Bald Mountain sequence from {{Disney/Fantasia}}.
** That terrifying brief moment after Elmer realizes his "twue love" is Bugs in disguise: Bugs runs away into the darkness of deformed canyon walls, the music turns ominous, and Fudd finally gets his helmet unstuck to scream, "I'LL KILL THE WABBIT!" with a berserker rage that would scare the Devil. This may be the one and only time his hatred of Bugs was played completely straight, without even a hint of humor.
* TearJerker: If an unintentional one, not unlike Chuck Jones' earlier ''WesternAnimation/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.
