Der Fuehrer's Face/YMMV


 * Anvilicious: it's a Wartime Cartoon so it is to be expected
 * Ear Worm: The title song.
 * Harsher in Hindsight/Funny Aneurysm Moment: The entire damn thing.
 * Memetic Mutation: The image of Donald Duck performing the Nazi salute with a swastika armband was very popular on Image Boards due to the sheer "what."-ness that it induced if you are unfamiliar with the cartoon.
 * Nightmare Fuel: The aforementioned Disney Acid Sequence.
 * Stealth Parody: Was actually reverse parodied many, many years later in "The Simpsons," when an episode talked about the history of Itchy & Scratchy and its creator, Roger Myers Sr. The concept falls into Older Than They Think for many younger viewers.
