127: Betty Cooper is a Moron

Explanation
The original story, "Batter Up!", involved Jughead crashing Betty and Veronica's tennis game. When Jughead writes tennis off as "for sissies," Veronica tells him it's only because he isn't good at it. Jughead snatches the racket [sic] from Veronica to prove he can play, but he calls it a "bat." When Betty corrects him, Jughead responds, "Hah! You're telling me?"

In this edit, Betty instead states that it is a "Zubat," apparently her term for a tennis racquet. Jughead corrects her as a Zubat flies past Betty. In  Pokémon  games, Zubat are commonly found in caves, where they are purported to swarm those who enter - the author's notes consequently refer to the Repel, which wards off wild Pokémon, and is thus indispensable for traveling through caves.

The author writes
This is what happens when you don't spray the Repel, Betty!
