- Tempting Fate: When Lincoln accuses Lucy of tossing the Princess Pony book in the toilet, she claims he has no evidence against her, only for one of her posters to fall down, revealing a Princess Pony poster behind it:Lucy: Dang it.
- Toilet Humor: Lynn's way of saying "take a dump" is "bomb[ing] the toilet", and never goes #2 on the same day of a roller derby game, before the game, considering doing so to be "bad luck" for her favorite team.
