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.
Award Snub: Despite making some of the most acclaimed shorts of the 40's, Tex never won an Oscar for any of his cartoons, and was lucky to be nominated twice—in contrast to the Tom and Jerry series winning seven Oscars and several nominations during this same time. This was notable enough to where an entire article was written about it on Cartoon Brew! Fortunately, Avery's films got a better reward later on—five of his films occupy The 50 Greatest Cartoons list (with four more as runner-ups) and one of his films even got inducted into the National Film Registry!
Keep Circulating the Tapes: Unedited versions of the shorts are rare, and outside of the Droopy cartoons, few of these shorts in have seen any DVD release. Fortunately, there was a Laserdisc set, "The Compleat Tex Avery" released which included ALL of Tex's MGM cartoons (including the two "banned" shorts "Uncle Tom's Cabana" and "Half-Pint Pygmy") uncut. If you look around online, you might just find it for a good price.
Values Dissonance: Many examples mock black people, while "Big Heel-Watha" and "Jerky Turkey" ridicule Native Americans.
The Droopy DVD set even includes a preface acknowledging this, as the shorts are completely uncut.
