YMMV / Joker: Folie à Deux

• Awesome Music: The trailer is set to a Sammy Davis Jr. & Tom Jones duet of "What the World Needs Now".
• Memetic Mutation: Steve Coogan's appearance as Arthur's doctor has led to many Alan Partridge jokes, many noting that Joker can hardly be blamed for his decline when someone like Alan is in charge of his mental health.
