The line you quote is the LAST line.I'm afraid I can only remember the first verse but I'll try to look up the rest for you. It may also jog someone else's memory...

It was Christmas Day in the workhouse The Eunuchs were sitting in pairs; Watching the Vestal Virgins combing their pubic hairs. When a voice from down the chimney went echoing round the walls, saying: "What do you want for Christmas?" And the Eunuchs all answered "Balls!"

Will get back to you when I find the other verses.
