Set up four chairs in the front/middle of the room. Tell the bride that you are going to see how well she knows her husband. Then, ask for the husband and three other men to come to the front and stand in front of the chairs. Now, blindfold the bride and tell her she has to pick out her husband by feeling the men's chests. She will feel each chest for a few seconds. After she is done, ask her if she thinks she knows which one is her husband. Then take her to her choice and have the man take the brides blindfold off.
