Hans and Rolf were walking home from the Beerhall late one night. Hans says 'Lets cut through the Graveyard'.
Rolf, having heard stories of strange happenings, declines his friend's offer and goes the other way.
The following day they meet up, Rolf says 'You made it then?'
'Yes' Hans replies, 'But something creepy WAS going on - I heard strange music in there so I recorded it on my phone - Listen!'
He plays a cacophany of Classical sounding music.
Rolf says 'That sounds familiar, play it backwards' Hans does so, and Rolf immediately recognises it 'That's Beethoven's 5th!' he exclaims. 'Let's meet tonight to investigate'
That night they meet at the graveyard and find a grave with the eerie music being played backwards wafting out - the grave is marked Ludwig Van Beethoven.
Hans whispers 'What's going on?'
Rolf replies 'It's obvious, he's decomposing'
