I'm sure I've posted this before, but it's a classic. I learned it from my 10 yr old (she's now 22).

Joy to the world that Santa's dead.
We barbecued his head.
And what about the body?
We flushed it down the potty,
And round and round it goes,
Round and round it goes,
Rou-ou-ou-ou-ou-ou-ou-ound
it goes.

Blessings,
Barbara
