Good King Wenceslas looked out of the bedroom winder
Silly bugger he fell out on a red-hot cinder
Brightly shone his bum that night
Though the frost was cruel
Till the doctor came in sight
Riding on a Mu-uel

Can't remember not knowing that! ...or...

Christmas is coming the goose is getting fat
Please spare a penny for the old man's hat
If you can't spare a penny a ha'penny will do
If you can't spare a ha'penny we'll put your window through...

Ah, Christmases of old!
