This is from the official PDFs South Park Studios was distributing last year...
"Mr. Hankey, the Christmas Poo"
Just then, from the depths of the toilet bowl, comes laughable, lovable MR. HANKEY, a jolly old piece of poo with a red and white Christmas hat.
MR. HANKEY: HOWDY HO!!!!
Hankey flies up into the air, bounces off a wall, and lands on the counter.
