Walking home after a girls' night out, two women pass a graveyard and stop to pee.  The first woman has nothing to wipe with, so she uses her underwear and tosses it.  Her friend, however, finds a ribbon on a wreath, so she uses that.  The next day, the first woman's husband phones the second woman's husband, furious: "My wife came home last night without her panties!"  "That's nothing," says the other.
