When working nights in the machine shop I put a kerchief on my head, rolled up my pant legs showing my boots and socks, and put a fleece lined coat on inside out with the sleeves rolled up. Then I went around the shop banging two bricks together and told the other 3rd shift machinists "Mewwy Clissmas" with my lower lip stuck out. Think it was about this time of year and NOT Christmas. Most thought it was hilarious.
Think it was right after management had come out with a new rule that you couldn't sleep on the toilets. A guy had fallen asleep, fell off the toilet and broke his arm.
