The Idea: Have the guests answer extreme/ hilarious etiquette questions.
Ground work: On index cards, write out a few wedding etiquette questions, the more outrageous the better. Think of some nuptial nightmares like:
What do you do if the best man sprays champagne all over the guests?
If you accidentally knock into the wedding cake?
If two bridesmaids get into a fight at the altar?
If you see a guest stealing items from the gift table?
How to Play: Hand out one etiquette card to each guest and have her write down an honest response to the situation. Then, have the bridal party gather all the cards and read the questions and answers aloud.
