The Beer Song

It is Sunday night and I am trying my hand at singing the kids to sleep. Destructo has lived up to his name over the past couple of weeks (poured Spitfire's sea monkeys over his head, banged her on the head with an empty plastic bottle, and destroyed her lego masterpieces with calculating skill),so I am thinking that he will succumb quickly after so much excitement, but he tosses and turns. Maybe I am off key? I sing Christmas songs that they like and that are soothing--Silent Night, Silver Bells, Little Drummer Boy. And then finally. . .silence. I make a move to get up when Spitfire pipes up and asks about that other song.
"What song?"
"You know. The one about beer on the wall."
