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: Spaceballs
Big Lipped Alligator Moment: The scene at the bar towards the end. It comes, it goes, it's not spoken of again, and seemed to only be there to give John Hurt his cameo.
Genius Bonus: Just before the Spaceball One transforms into Mega Maid, Dark Helmet orders, "Commence transformation!" Then, he asks under his breath, "Ready, Kafka?" The comment is a reference to Franz Kafka's short story "The Metamorphosis, in which a young man wakes up to find that he's turned into a giant cockroach. Normally, one shouldn't explain the joke, but this was very subtle.
Hilarious in Hindsight: Yogurt says that, "God willing, we'll all meet again in Spaceballs 2: Da Soich for More Money". And they do indeed meet again...in Spaceballs: The Animated Series, which is an obvious (and unfortunate) cash grab made by people who apparently only ever heard that line.
Some behind-the-scenes video of Star Wars as it was being filmed reveals that David Prowse, Darth Vader's body actor, has a voice very similar to Rick Moranis.
Part of the plot! Space heroes rescue space royalty from bad guys. While the good guys are escaping, they drain their spacecraft's energy and have to land on a desert planet, where they find a powerful being. Sound familiar?
