Trivia / Grumpy Cat's Worst Christmas Ever

• Throw It In!: Aubrey Plaza, the voice of Grumpy Cat, said that when she was brought in to record, most of Grumpy's dialogue wasn't written or finalized yet, and she was asked to just make up her own lines for Grumpy. Plaza spent most of the recording sessions watching the live action footage and riffing on whatever action she saw. She even went far as saying the recording sessions were "like my own MST3K".
