The Real Santa

"So, I hear you want a blue bike for Christmas," states Phillip.

"Um, yes. How do you know?" replied Mollie.

"Santa knows all."

"Yeah, but you aren't the real Santa."

"Non-believers get nothing for Christmas."

"OK?"

"Do you believe in me or not?"

"Sure?"

"You get nothing! Marble, this friend of yours is awfully naughty," exclaims Phillip.

"I think she's just hungry," replied Marble.

"That explains a lot."
