Mum... if Santa has to deliver all of the presents to all of the children in one night, he would need to go at 3,000 times the speed of sound... which is impossible.

Santa

CALVIN: This whole Santa Claus thing just doesn't make sense. Why all the secrecy? Why all the mystery? If the guy exists why doesn't he ever show himself and prove it? And if he doesn't exist what's the meaning of all this?
HOBBES: I dunno. Isn't this a religious holiday?
CALVIN:Yeah, but actually, I've got the same questions about God.
