Chekhov's Classroom
Pay attention in class, especially science class, because you will need the information later in the episode.

This trope is the awkward tendency of programs to use precisely what they learned in school (almost always science) earlier that episode, and to lampshade it through grating dialogue. Shows aimed at an older audience can make it slightly more subtle; even so, it usually comes out like this:
"Oh no! We're being attacked by Gef the Talking Mongoose. Wait a minute, say, Swotty McCliche, weren't you studying how to defeat talking mongooses just this morning?"
"Oh yes, I totally forgot. How conveniently stupid of me!"

Common in Edutainment Shows. May be the payoff for a Reading Is Cool Aesop.

Compare Strange Minds Think Alike and Lecture As Exposition.
