Beethoven dies and is buried. A couple of months later, a man walking through the cemetery hears strange noises coming from Beethoven's grave. The man runs to get the town magistrate, and brings him to the grave where the noises are continuing. The magistrate puts his ear to the grave and listens for a few moments.
"Ah yes, that's Beethoven's 9th Symphony, being played backward" says the magistrate. He listens a while longer. "Now it's the 8th Symphony being played backward...there's the 7th...the 6th...the 5th..."
The magistrate stands and turns to the man. "You fool," he exclaims, "you called me away from supper for this? There's nothing to worry about. It's just Beethoven decomposing!"
