Halls of the Dark Muse

So once upon a time ago, there use to be this really obnoxious TV show for kids called Barney (some of you may be famillair) it was a big sensation for a while, and basicaly stared this dude dressed up in a big purple dinosour costume. Well there was this reallly annoying "happy" song that he always sung. Well completely out of the blue for no apperently reason the tune of the song popped into my head and I started making up my own lyrics for it to amuse myself and this is what restulted:

I killed my girlfriend
in the shed
dug a great big hole
to burry her bones in
now they will never
find her again.
