A man was walking past a graveyard and he heard one of Beethoven's symphonys playing backwards. He thought to himself "That's weird" and kept walking.

The next day the same man walked past the same cemetery and heard another one of Beethoven's symphonys playing backwards. He thought to himself, "Now that's REALLY weird!" and kept going.

The next day the same man was once again walking past the same cemetery and heard "Ode to Joy" playing backwards. The man said "I can't take this any more!" He walked up to the caretaker and asked, "What is going on around here?!"

The caretaker answered, "Oh, that's just Beethoven decomposing."
