Here's but one:

On November 6, associate editor David Schmader was walking to the Stranger election night party at the Showbox when he saw a novelty T-shirt in a downtown shop window. On the front of this T-shirt was the much-appropriated British wartime slogan "Keep Calm and Carry On," presented in the classic vertical column, but with the text modified to read "Keep Calm and Gangnam Style." Mr. Schmader regrets that in 20 years, a sitcom will use this T-shirt as a visual symbol for our entire decade.
