Singing at the dinner table

Adam and I were serenaded tonight by the kids with a spontaneous chorus of the Futurama version of "Santa Claus is Coming to Town".

He knows when you are sleeping.
He knows when you're on the can.
He'll hunt you down and blast your ass from here to Pakistan.
Ohh.
You better not breathe, you better not move.
You're better off dead, I'm telling you dude,
Santa Claus is gunning you down.

I'm so proud :D

(Adam suggested they sing it at next year's school talent quest.)
