These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
YMMV: Bugs Bunny
Accidental Innuendo: In Invasion of the Bunny Snatchers, Bugs sticks the Nudnik copies into a burlap sack, but the exact dialogue when he starts:
"Get in the sack, Evil Twin. I've got plans for you."
"Funny Aneurysm" Moment: In "Falling Hare", Bugs narrowly stop the Gremlin from crashing into a pair of identical twin skyscrapers by flying in between them. Not sixty years later...
Hilarious in Hindsight: In 'Rebel Rabbit' bugs finds out that the reward for Foxes is $50, but the reward for rabbits is $.02. When he goes to Washington to complain about this, he's told its because Foxes are destructive, but rabbits are harmless... Maybe Bugs decided to prove them wrong by sending some relatives down under.
Sophomore Slump: The second official Bugs cartoon, "Elmer's Pet Rabbit" is commonly regarded as one of the worst in the series, owning to Bugs's extremeJerk Ass behavior, off-model use of yellow-colored gloves, a voice that doesn't sound anywhere close to his iconic semi-Brooklyn accent, as well as the sloppy timing that Chuck Jones's earlier efforts suffered from.
In fairness, "Elmer's Pet Rabbit" is only nominally considered to be a Bugs Bunny cartoon. Warner Bros. slapped a "Bugs Bunny" title card at the beginning of the cartoon to quickly exploit the unexpected success of the previous A Wild Hare. In actuality, both cartoons were in production at the same time using different variations of the goofy grey rabbit Looney Tunes had been using in numerous cartoons at that point. "Tortoise Beats Hare" is the more proper second Bugs cartoon.
Ugly Cute: Witch Hazel in "Bewitched Bunny". Her reaction to Bugs finding Hansel and Gretel ("Call it a weakness.") is almost Moe.
In "Broomstick Bunny", the ugly, fat, green-skinned Witch Hazel accidentally gets transformed into a beautiful, slender, white woman by drinking a beauty potion. When she consults her magic mirror, the "genie" in the mirror instead tries to grab her, and then pursues her on a magic carpet as she attempts to flee on her broomstick. This is treated by Bugs (and clearly meant to be seen by the audience) as funny. Made rather more awkward by the fact that the genie is plainly depicted as being a black man. At the time the cartoon was made interracial relationships were still quite controversial in American society. A common slur against African-American men was that they all wanted to rape white women.
Values Dissonance: "All This and Rabbit Stew", and most infamously, "Bugs Bunny Nips The Nips". The latter even got the first "Golden Age of Looney Tunes" laserdisc set recalled when it was included on it, replacing it with Racketeer Rabbit. If you can find an unaltered copy of that laserdisc set with the Nips cartoon on it, you've got a nice collectors item on your hands.
