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: MGM Oneshot Cartoons
Crowning Music of Awesome: "The Blue Danube", from the short of the same name; and this version even has custom lyrics made for it!
Ear Worm: "Tom Turkey" has a soundtrack composed entirely with harmonicas.
Keep Circulating the Tapes: Many of these oneshots are not available on DVD, although Jerry Beck's Cartoon Research Web site has (unrestored) prints available for historians to study. However, they did air during the 1990s on Cartoon Network and Toon Heads (and continued to air very early in the morning on Boomerang until June 2014), and at least one VHS release included some of these shorts.
