I'm going to guess that he's either driven off the road in the snow, or that the power is out.
Or that terrorists stormed the house and took him captive as he's the only one who knows the secrets of The Tomb of Akbara-Habishini.
Or that looters rampaged through the house, killing his father and making off with much in the way of Costco volume shopping booty and guns. Lots and lots of guns.
And Chad just can't pull himself away from him celebratory booty dancing out in the front yard.
It's only 10 o'clock his time.
I am not worried.
