Blindfold the groom (you don't want to mess up the bride's makeup). Put 4 different colored (flavored) life savers in the Bride's mouth. Have the Groom fish each color out in a specific order (get the audience to choose). For each one he gets wrong, he has to do a drink (if he has been drinking too much may I suggest a full glass of water for each error)
Pop the Balloon
Get the wedding party out and place a balloon between each woman and man (use your imagination of where to put the balloon). They have to hug tightly enough to break the balloon. The last one to do it is punished. (Do not fully inflate the Newlyweds balloon - it makes it harder or impossible to pop). Punishments can be anything from kissing, to singing , to carrying the bride around the room, etc...
Same as the Newly Wed Game - When the Bride leaves the room to change (or powder her nose) ask the groom some questions about them to see if the Bride answers the same when she returns. For each wrong answer you can offer a punishment. Sample Questions would be: What was the other person wearing when they met? Does the other person like their toilet paper to roll off the top of the roll or the bottom? Who is smarter, the bride or the groom and why?
You can also use do the above game with the bride and groom taking off their shoes and exchanging one of theirs for their spouses. Make the questions so that they have to answer with either a him or her. For example, "who will be the one who takes out the garbage?" The newlyweds would then hold up the shoe that corresponds with who they think is going to do it. Of course the couple have to be back to back so they cannot see how the other responds!
Blind fold the participant and have him or her feel a certain body part of some volunteers and then their spouse (remember your doing a family show here!). Then he or she has to guess which one was their partners.
