I know I missed the Halloween boat a little bit on this one, but I heard this on the radio actually on the day of Halloween and thought it was an interesting extension of a previous fun fact.
If you read Fun Fact #137, you know that Vincent Price (who voiced Vincent Van Ghoul in The 13 Ghosts of Scooby-Doo) recorded uncredited vocals on Michael Jackson's "Thriller," which was parodied in the intro for the The New Scooby-Doo Mysteries.
What you may not know is that Vincent Price recorded his part in only two takes and received $1,000 for recording these lines. According to Mental Floss, Price later became very frustrated after he learned the music video cost $500,000 to make, and argued that his paycheck was grossly unfair given the large budget used to make the "Thriller" video. Michael Jackson later completely stopped talking to Price and ignored his calls because of this incident.
