True stories:

CALLING CARD: The recent 67th annual convention of the American
  Association for Nude Recreation in Dawsonville, Ga., was not welcomed
  by area businesses until the owner of the nude resort hosting the event
  passed out 1500 $2 bills for the conventioneers to use while shopping.
  Paying with the rarely seen bill brought attention that the customers,
  who of course wore clothing while in town, were nudists, the
  Association says. Once the merchants saw how many people were using the
  bills, they threw their shop doors open wide to the nudists. "Their
  money is as good as mine," enthused one restaurant owner. "They can
  come in here and eat naked if they want, as long as they pay." (Wall
  Street Journal) ...Area gay groups like the idea, and are considering
  passing out $3 bills.
