He's Got a List, He's Checking It Twice

Little Tommy sat bolt upright in bed. He'd heard something creak on the roof. Opening his bedroom window, he heard the unmistakeable sound of sleigh bells above. Santa!!

Santa lit a fag and sat back in his sleigh.
"Number 6, Patrick McGoohan Grove...let's see..." he pondered, rummaging in a sack of presents.
Rudolph turned his head to look at him. "Not this one" the reindeer said, bluntly.
Santa stopped searching, and reluctantly pulled a hand grenade from his pocket. He sighed, plucked out the pin, and approached the chimney.
"Do it" Rudolph instructed.

Santa dropped the grenade.
Rudolph nodded, smiled.
