My daughter came home from third grade school playground singing that Barney song, the Robin/Batman parody and

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

She also had a singing and 2 person clapping game "When Susie was as baby... ( different things)" that ended with "Oo, Ah, lost my bra" and the gesture of crossing your hands over your chest. I'll ask her in the morning how it went.
Blessings,
Barbara
