User: Why is the Michael Jackson song ‘Thriller’ called ‘Thriller’?
Assistant: The song is called Thriller because it’s about a serial killer. The song is about a man who is obsessed with a serial killer, and he wants to find him. The killer is named Jack the Ripper, and he is described as a man with a hook nose and a scar on his face. The song is also about a dance contest, where the winner gets to kill the loser.
