The Twenty and the One

      A well-worn one dollar bill and a similarly distressed twenty dollar bill arrived at a Federal Reserve Bank to be retired.  As they moved along the conveyor belt to be burned, they struck up a conversation.  The twenty dollar bill reminisced about its travels all over the country.
      "I've had a pretty good life," the twenty proclaimed.  "Why I've been to Las Vegas and Atlantic City, the finest restaurants in New York, performances on Broadway, and even a cruise to the Caribbean."
      "Wow!" said the one dollar bill. "You've really had an exciting life."
      "So, tell me," said the twenty, "Where have you been throughout your lifetime?"
       The one dollar bill replied, "Oh, I've been to the Methodist church, the Baptist church, the Lutheran church..."
        The twenty dollar bill interrupts, "What's a church?"
