In Morty's MindBlower (Rick and Morty S3E8), when Morty told Principal Vagina that Mr. Lunas was "up to something" and "lives on the moon", Principal Vagina thought "lives on the moon" was a hint that Mr. Lunas was a pedophile. This could be seen from the conversation between him and Morty after he confronted Mr. Lunas and punched him in the face:
M: What did he say?
P: Denied the moon stuff, but that's what pedophiles do, they deny, it's their bread and butter.
P: You don't think so? I thought the moon thing might have been code.
M: No, he's literally from the moon!
P: Well, you saw him react. Moon or not, that dude likes 'em young.
My question is, why would Principal Vagina take the moon stuff as "code" for pedophilia? There is absolutely no connection between the two as I can see.
