History WesternAnimation / WhatsUpDoc

** In the sequence where Bugs is in the traveling vaudeville show with Elmer and decides to come up with a new act so he won't be made a fool like he was in the previous scenes, the version that aired on ABC cut a slightly risqué joke between Elmer and Bugs (see DropTheHammer) and the part where Elmer holds a rifle to Bugs' mouth after Bugs upstages him. On ABC, after Bugs decides to change the act, it cuts to Bugs saying "Eh, what's up, doc?" while Elmer aims the gun at Bugs, with no explanation as to what caused it. This part was also cut when it aired on The WB.

* DropTheHammer: Bugs uses a mallet (and a PieInTheFace and seltzer sprayed from a bottle) to deliver the punchline in his third performance with WesternAnimation/ElmerFudd:
--> '''Elmer:''' Say, pinhead, do you know how to make anti-fweeze?\\
'''Bugs:''' Yeah! Hide her nightgown!

* ShownTheirWork: Overlaps heavily with ItWillNeverCatchOn here. For those on the inside, picking winners and losers is often hit-and-miss.

** In the park bench segment, [[NoCelebritiesWereHarmed caricatures]] of Creator/AlJolson, Creator/JackBenny, Creator/EddieCantor, and Creator/BingCrosby are shown lined-up and slumping, indicating an out-of-work phase. As they try to impress Elmer with their signature acts ("Mammy" for Jolson, Kreutzer's Etude No.2 for violin for Benny, a dance to "Ain't We Got Fun" for Cantor, and "You Must Have Been a Beautiful Baby" for Crosby), he passes on all of them, claiming to Bugs "they'll never amount to anything!" Doubles as HypocriticalHumor in the case of Cantor, since he co-wrote and originated "Merrily We Roll Along", the song used for the ''Looney Tunes'' fanfare.

* StandardSnippet: Hungarian Rhapsody #2 on the toy piano.

* TitleThemeTune: The song Bugs performs during his screen test with Elmer (which would be used instrumentally in many other Bugs-related ''Looney Tunes'' shorts and even the 1990s ''Merrie Melodies'' show).

-->What's up, Doc? What's cookin'?\\

Eh, what's up, Doc?

* TitleDrop: The song Bugs performs during his screen test with Elmer (which would be used in many more Looney Tunes-related features and even the 1990s ''Merrie Melodies Show).''

* CallForward: One of the shows that Bugs "starred" in is called "Wearing of the Grin". A year after this cartoon was released, a WesternAnimation/PorkyPig cartoon was released with this title.

''"We know you're rooting for us. But we have to gooooo..!"''

----

Produced to coincide with the tenth anniversary of the rabbit's first appearance (in ''WesternAnimation/AWildHare''). Not to be confused with the 1972 live-action film [[Film/WhatsUpDoc of the same name]].

* ThemeTuneCameo: When Elmer discovers Bugs, "Merrily We Roll Along", the theme for Merrie Melodies, plays, since Bugs was often associated with that theme.

* MilestoneCelebration: The 10th anniversary of WesternAnimation/BugsBunny.
