S2E3 The Star Strangled Banner

Title: The Star Strangled Banner Plot: The future of music hangs in the balance when Missy Mom is chosen to perform the national anthem at the San Dimas baseball game. Unfortunately, her performance is so off-key that it makes Roseanne Barr’s infamous rendition sound impressive by comparison! As the crowd reacts in shock, the implications for all musical expression become increasingly dire, leaving everyone to wonder if music will ever recover from this disastrous show.
