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: Mario Paint
Big Lipped Alligator Moment: The exercise scene. After the title screen, the game plays a short, black-and-white animation of sit-ups and a handstand, while the crowd cheers. Brental Floss used this scene in a video with the comment, "Seriously, wtf was this about? Seriously."
Cult Classic: Although it didn't sell well when it was released, it has become popular now, especially due to its fly-swatting game and YouTube videos of songs made in Mario Paint.
Sidetracked By The Golden Saucer: The fly-swatting minigame, especially considering half of the main trope page is about it. In later years, the music composing section became this in spades, to the point where finding footage of anything besides it on YouTube is a challenge.
