A daring vacationer in Vienna is walking through a graveyard on Halloween when all of a sudden she hears music. No one is around, so she starts looking to see where it's coming from.
She finally locates the source and finds it is coming from a grave with a headstone that reads, "Ludwig van Beethoven."
Then she realizes that the music is the Ninth Symphony and it is being played backward. Puzzled, she leaves the graveyard and persuades a friend to return with her.
By the time they arrive back at the grave, the music has changed. This time it is the Seventh Symphony, but it is also being played backward.
Curious, the ladies agree to consult a music scholar. When they return with the expert, the Fifth Symphony is playing and the expert concludes that the symphonies are in fact being played in reverse order.
By the next day the word spread and a huge group gathered around the grave to hear the Second Symphony being played backward. Just then the graveyard's caretaker approaches the group. Someone in the crowd asks him if he has an explanation for the music.
"Oh, it's nothing to worry about" says the caretaker. "He's just decomposing!"
