A holiday celebrated on December 23. I began in 1264. It started when the neighbor kids were running around the Blacksmith at work. He then dropped his anvil on them because they disracted him. He lied and said that they were "screwin' around too much" Ever since then, He dropped anvils on the kids that "screw around too much" heads as a warning that they should get coal for X-mas.
"Happy Anvil day!!, don't screw around"
