And then tomorrow comes and I will be far away
Give a cry or give a whistle
Watch out for that old man Fritzl
He will have you in a hole
I have seen and I have heard things
May all be misunderstandings
Down where it's dark and black as coal
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.
