" 'Hello, babies. Welcome to Earth. It's hot in the summer and cold in the 
  winter.  It's round and wet and crowded. At the outside, babies, you've got 
  about a hundred years here. There's only one rule that I know of, babies-- 
 'God damn it, you've got to be kind.' " 
        --Kurt Vonnegut, God Bless You, Mr. Rosewater
