YMMV / Star vs. the Forces of Evil S2 E31 "Running with Scissors"

• Fanfic Fuel: The sixteen years that Marco spent as a badass warrior chasing down Hekapoo.
• Memetic Mutation: "BYEEE!" Star may have only said this once in the series, but it later gained popularity when Eda and Hunter pantented the saying. It's also used by other Disney animated characters such as Hopediah Plantar, Scratch and Andrea Davenport; even Raven Baxter took to saying it.
• They Wasted a Perfectly Good Plot: Not in this episode but the ones that came after it as Marco returns to his normal self (personality-wise) with the writing team saying that Marco has forgotten most of the sixteen years chasing Hekapoo even through the episode ended implying that he was going to have troubles re-adapting to his normal life.
