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.
Alternative Character Interpretation: Goofy was hit hard with this in Kingdom Hearts. In every instance of him before the series, he was just the lovable guy, if a bit of an overbearing parent. In Kingdom Hearts, especially in the second installment, he's actually more down to Earth, and has the most common sense of the trio. He was the first to realize Mulan was a girl, and the first to link that if Xehanort was a strong enough being when he became a Heartless, then he would have probably also have a Nobody.
Ear Worm: The Pogo Stick song from Victory Vehicles is insanely catchy.
Hilarious in Hindsight: During the last few minutes of Hockey Homicide, when the confusion over many extra hockey pucks leads the players and spectators into a massive brawl, recycled clips from the two Goofy episodes, How to Play Football and How to Play Baseball, as well as clips from other Disney cartoons (Victory Through Air Power and the Monstro scene from Pinocchio) are added in to emphasize the confusion. These last minutes are something that only YouTube Poop would love.
Memetic Psycho Path: Some iterations of the "It's Goofy Time" meme depicit him as a vicious child abuser.
Nightmare Fuel: Goofy's attempted suicide in "The Goofy Success Story" from the Disneyland series.
