Toilet Paper Mystery Game

As guests arrive, hold out a roll of toilet paper and ask each guest to tear off whatever length of toilet paper they think they'll need. Don't explain what it's for but you might say something like "We're short of toilet paper tonight, and I wanted everyone to have some before we ran out." At some point in the hen party gather the guests and measure the bride's bust, hips, leg length, or whatever with the strips of toilet paper. The guest with the closest length of toilet paper wins.
