"I sat around all night under the chimney, holdin' my sac like "gimmie! gimmie!"
-- Insane Clown Posse in Santa's a Fat Bitch

Santa is mind control. The parents use Him as a means to get their kids to behave for a month or so every year. "You better watch out. You better not cry. You better not pout, I'm telling you why: Santa Claus is comin' to town."

Be good if you want presents. You want presents, don't you? Toys galore! Be good and you'll get toys! Toys are what bring true happiness. Be good and you'll get toys. Be good. Be good. Be good.
You weren't good! I'm going to call Santa on the phone and tell him.
(I thought "He knows if you've been bad or good".) You'd better be extra good from now on if you want presents. Presents. Toys. Be very good and you'll get lots of toys. Be good. Be good.
