"The moral of this story is to have all the fun while you can because one day you're going to be really, really, irreversibly dead."
This is a cover of an old Irish folk song which explains why it's probably a bad idea to go shooting after dark.
Eamon McNelis, who wrote and sung this song, previously dated Mary long before she became a princess. He decided to dump her, whether it was because of her yappy dog or the fact that she was just boring, we don't know. What we do know is that as she gained fame and started popping up in newspapers and magazines, the less he could have her and the further away she got, and the more Eamon wanted her.
Old man Fritzl is a reference to Josef Fritzl, a man who locked his own daughter in his cellar for 24 years and fathered seven children with her.
If ever you get to a point in your life when you feel like you want to lock someone in a basement, The Boogieman is a reminder not to.
