You're probably thinking of "All This and Rabbit Stew", which is also on the Censored 11 list. A 1941 Tex Avery cartoon, it pits a black hunter (sometimes called Sambo by those who've seen the cartoon) against Bugs in a series of spot gags, much akin to "A Wild Hare" a year earlier, but wilder and more fast paced. Bugs one-ups the hunter in a dice game in which he wins the hunter's clothes (and there's a very funny gag at the end of the cartoon in which the hunter stands there, wearing nothing but a fig leaf, and says "Well, just call me Adam!" - and as the iris closes on the cartoon, Bugs rushes in, reaches through the hole, and grabs the leaf to display it to the audience).
It's the only Bugs Bunny cartoon on the Censored 11, but it's by no means the only Bugs cartoon to be banned. The cartoon is also part of the 12 Missing Hares, which were a series of cartoons that were withheld from Cartoon Network's 2001 June Bugs marathon. Among the others are:
- "Hiawatha's Rabbit Hunt" (banned for its portrayal of Native Americans)
- "A Feather in His Hare" (also banned for its portrayal of Native Americans)
- "Horse Hare" (same as the above two cartoons)
- "Mississippi Hare" (banned for its setting of the slavery-era Southern United States)
- "What's Cookin', Doc?" (banned for featuring a lengthy clip of "Hiawatha's Rabbit Hunt)
- "Frigid Hare" (banned for its portrayal of Eskimos)
- "Any Bonds Today?" (banned for a scene in which Bugs does a blackface impression of Al Jolson)
- "Bugs Bunny Nips the Nips" (banned for its wartime portrayal of the Japanese)
- "Herr Meets Hare" (banned for its depictions of Hermann Goering and Adolf Hitler)
- "Witch is Which?" (banned for its portrayal of African natives)
- "Bushy Hare" (banned for its portrayal of Australian natives)
Since "Frigid Hare" was on the first Looney Tunes Golden Collection, and "Mississippi Hare" is slated for the fourth, I think it's safe to say that Warner Bros. Home Video doesn't have the same qualms with these cartoons that Cartoon Network did.
