The Who pudding?
If you hate all this jolliness, we can't blame you in the least. The Roast Beast? The Christmas feast? It's a latex molded mask so you can wear the mug of your favorite Who from Whoville. The singers singing? Don't worry, it has holes to hear, eye-mesh to see, merely pop it on and you'll be green as a Christmas tree! Perhaps a metaphorical expansion: from a previously scrooge-like outlook on the holidays to something far more happy.
