- Accidental Innuendo: In "My New Friend Is So Fun!", Gerald and Snake celebrate their thought that Piggie and Brian are having so much fun, until they stop and realize that they may be having too much fun. Can come off dirty to older audiences...
- Hilarious in Hindsight: To anybody who has seen a certain episode of South Park. There is an episode called: "An Elephant Makes Love to a Pig."
- Viewer Gender Confusion: Due to a lack of Tertiary Sexual Characteristics and the books being written entirely in dialogue with no narration, it's easy to assume that Piggie is male.
YMMV / Elephant & Piggie
