* {{Fanon}}: After they were redesigned on ''WesternAnimation/TinyToonAdventures'', some fans headcanon that Bosko and Honey are [[WesternAnimation/{{Animaniacs}} Yakko, Wakko, and Dot]]'s real parents, seeing as how ''WesternAnimation/WakkosWish'' most likely isn't canon to the main ''Animaniacs'' series.
* FairForItsDay: Still hotly debated today, and it's complicated by the fact that Bosko's race is sometimes unclear (and complicated further by WordOfGod claiming they didn't see him as black); but when he ''is'' portrayed or seen as black, while his look and feel are based on blackface minstrel shows that are generally seen as heavily offensive today, he's also generally portrayed as intelligent, kind, and heroic, while sometimes fighting and defeating villainous white antagonists.
* HarsherInHindsight: In "Bosko's Picture Show", there is a short scene of UsefulNotes/AdolfHitler (in what is now considered the first time he's been caricatured in a Warner Bros. cartoon) chasing a caricature of Creator/JimmyDurante with an axe. Although Durante was Catholic, not Jewish, it still stood that his most prominent (and thus, most comically exaggerated) feature was his large nose, which is associated with Jewish caricatures.
* HilariousInHindsight: The newspaper Bosko reads in "Bosko's Mechanical Man" is called the [[ComicBook/SpiderMan Daily Bugle.]]
* ReplacementScrappy: Buddy is universally disliked by fans of the series, with both the character and his cartoons seen as a bland as wheat replacement for the fairly fun Bosko cartoons.
* SeasonalRot: The later Bosko cartoons got a lot blander and had much less frequent, tamer gags than the earlier Bosko shorts, in spite of the animation getting more polished. The ''WesternAnimation/HappyHarmonies'' Bosko shorts are likewise considered inferior to the earlier shorts, mainly for their cloying, sluggishly paced nature and weak gags, despite their exquisite artwork.
* {{Squick}}: In "Bosko's Party", one of the guests hides in a chamber pot.
* TakeThatScrappy:
** Bosko (and Buddy) shorts were run alongside other ''Looney Tunes'' shorts on Nickelodeon for a time. At some point they removed them and ADVERTISED IT, with an ad that went like: "See all your favorite characters! More Bugs! More Daffy! ...''and no Bosko''! Sorry, Bosko!" This accompanied a short animation of Bosko in a closing IrisOut. No Bosko (or Buddy) cartoons were ever shown again.
** Buddy's return in ''WesternAnimation/{{Animaniacs}}'' got him an entire episode that gave him this treatment.
* ValuesDissonance:
** The MGM shorts featuring him due to his redesign as a black human boy with bright, pronounced lips.
** The early ''Looney Tunes'' entries gave him a stereotypical Southern drawl, but later shorts gave him that WesternAnimation/MickeyMouse falsetto voice [[FollowTheLeader every cartoon character in that era had]].
** Even when putting aside the controversy over whether or not Bosko was meant to be a black caricature, the scene in his debut short where he performs a stereotypical Jewish song and dance is ''very'' offensive by modern standards.
