For Whom the Sleigh Bell Tolls – American Dad

Stan and Steve accidentally shoot Santa Claus with the new gun that Stan bought Steve for Christmas setting off a war between The Smith family (and Bob Todd the moonshiner) versus Santa’s forces. The bloody brawl on the moonshiners mountain is so crude and full of so many funny bits not the least of which is Roger, Francine and Hayley using their mouths to fashion candy cane into pointy interments of war.
