'Twas Christmas Day in the harem
The eunuchs were sitting on chairs
Watching the Vestal Virgins
Combing their pubic hairs.
When suddenly Father Christmas
Came striding through the halls,
And said, "What do you want for Christmas?"
And the eunuchs cried out "BALLS!"

An old army song,sung to the tune of the "Eton Boating Song". There is another verse about the sexual proclivities of the camel, but we'll draw a veil over that one.
A little seasonal ribaldry to get me back in the mood for blogging.
