j.k. rowling: Harry had never in all his life had such a Christmas dinner. A hundred fat, roast turkeys; mountains of roast and boiled potatoes; platters of chipolatas; tureens of buttered peas, silver boats of thick, rich gravy and cranberry sauce — and stacks of wizard crackers every few feet along the table... Harry pulled a wizard cracker with Fred and it didn't just bang, it went off with a blast like a cannon and engulfed them all in a cloud of blue smoke, while from the inside exploded a rear admiral's hat and several live, white mice.
