Last Saturday, my friends and I were heading for a subway station in Brooklyn and found ourselves behind a man and a woman both dressed in Santa Claus outfits. They were kind enough to wave us onto the train with a "hurry, hurry!", and we made it on board just as the subway doors closed.
And then we discovered that we were on a subway train filled with people dressed as Santa Claus, noisy but well-behaved. What parallel universe had we mistakenly stepped into? Was there some subway dress code announcement we had missed?
