* In the WhateleyUniverse story "Ayla and the Tests", Phase misses several days of school and gets a big lecture in the lab section for Powers Theory class from Dr. Yablonski on Warper powers and warp displacement fields of 'giants' (Warpers who use their power to apparently grow to huge size). In a LampshadeHanging, Phase even refers to him as MisterExposition. Guess what Phase faces when they go to Boston? A forty-foot giant who's a warper.
** In "Ayla and the Birthday Brawl", Ayla shows (s)he knows too much about taking out mutants with powers, and she talks all about it on the way back from martial arts class. What she says about fighting Package Deal Psychics saves Lancer's life in the big final fight.
** Of course, Whatley Academy ''is'' a SuperHeroSchool, so it's more than usually justified.
* The [[KidHero students]] at the [[GlobalGuardiansPBEMUniverse Hyperion Academy]] used the information they learned in about electro-magnetism during their weekly physics class to defeat the villainous Lodestone.
* {{Lampshaded}} in AVeryPotterMusical: at the beginning, Snape asks if anyone knows what a Portkey is. His next question is if anyone knows what {{Foreshadowing}} is.
