At a K’nex toy factory in Pennsylvania, President Obama says he’s been keeping ‘Naughty and Nice list’ in Washington as the fiscal cliff negotiations continue.

"I've been keeping my own naughty and nice list for Washington," Obama said. "So you should keep your eye on who gets some K'NEX this year. There are going to be some members of Congress who get them, and some who don't."

Obama added that if Congress doesn’t pass tax cut extensions for the middle class, Americans would find a rude awakening on Christmas morning.

“That’s sort of like the lump of coal you get for Christmas,” Obama said sternly. “That’s a Scrooge Christmas.”
