* HeyItsThatVoice: Well, not so much Humphrey, but J. Audubon Woodlore, the ranger that runs the park Humphrey lives in, was voiced by Bill Thompson, who also voiced such characters in [[DisneyAnimatedCanon Disney animated features]] as [[Disney/AliceInWonderland the White Rabbit]] and [[Disney/PeterPan Mr. Smee]] (as well as Droopy at {{MGM}}).
** In the 1930s, the Big Bad Wolf was voiced by Billy Bletcher, the original voice for {{Pete}}. Fittingly enough, on ''HouseOfMouse'', he was voiced by {{Pete}}'s current voice actor, Jim Cummings.
** Also in the 1930s, Practical Pig was voiced by Pinto Colvig, the original voice for {{Goofy}}. Fittingly enough, on ''HouseOfMouse'', he was voiced by Goofy's current voice actor, Bill Farmer.
* KeepCirculatingTheTapes: There are still a handful of classic Disney shorts that didn't make their way into the Walt Disney Treasures lineup, including two of Goofy's 60s shorts, ''Freewayphobia #1'' and ''Goofy's Freeway Troubles'' ("How to Ride a Horse" and "El Gaucho Goofy" from the 40s aren't counted here, as they was technically part of other features, the former as part of ''The Reluctant Dragon'' (and can be found intact on Walt Disney Treasures: Behind the Scenes At Walt Disney Studios) and the latter as part of ''Disney/SaludosAmigos''), Chip 'n Dale's three solo shorts (although they are available on VHS and some of them on DVD) and poor little "Susie the Little Blue Coupe" didn't get into the Disney Rarities set (although it has somehow made its way onto public domain [=DVDs=] like Bazooka Joes cartoons, as well as included on DVD releases of ''Disney/TheAdventuresOfIchabodAndMrToad'' and ''Film/TheLoveBug'' as extras and as part of a series of [=DVD=]s called "It's a Small World of Fun"). They have also only released a select few of the early Alice Comedies on the Disney Rarities and Oswald the Lucky Rabbit sets, but many others are available via VCI and Inkwell Images DVD collections. Also, the obscure Disney short about "Menustration" hasn't been officially released, but has fallen into the public domain. Donald is also missing three shorts from the 1960s ("Donald's Fire Survival Plan", "Steel and America" and "Family Planning"), and two '60s oneshots "Scrooge [=McDuck=] and Money" and "It's Tough To Be a Bird" have also not received a release.
* MissingEpisode: Several AliceComedies and OswaldTheLuckyRabbit shorts aside, none of the sound or color shorts are lost. However, original prints of many of them containing their original title screens currently are lost and the MickeyMouse shorts ''When the Cat's Away'' and ''The Jazz Fool'' currently lack their opening music.
* OldShame: Director Wilfred Jackson disliked the early Mickey Mouse short "The Castaway", and from it's completion vowed to never again make another picture that didn't feel like a Disney cartoon, according to TheIllusionOfLife: Disney Animation.
