The bride is blindfolded and is handed a box. She opens the box and tries to guess what's inside it by touching or smelling the object. She should be given at least 5 different objects (be sure to prepare things she can use on her wedding night) to identify. After she guesses all the objects, her blindfold is removed and each object is revealed. This is quite hilarious because, most of the time, the bride can't guess an object right.
