What is a good party idea that involves paring people up?

Have your friends write up number of questions they would like to ask a perfect stranger, blind fold each one and give them a number , lead to a room in different parts of the house to be questioned. Then your friends choose which number is to their liking . Pair them off and have different exotic food stations. such as a cocktail station, fruit, ice cream with different toppings but, one spoon per couple and a pressed sandwich station using like pound cake with different fillers, like,banana, strawberries, and chocolates. have fun your friends will be talking about this party for years.

you could do relay race type things, potatoe sack races,lol, or like that game where u test ur partner blindfold them and the other leads them around a course....have a fun party :)

find your match... give everyone a half a card (from a deck of cards) You need to find the other half in the crowd. Fun and gets people talking to each other.

how bout a treasure hunt? You can try to invent a more mature one since it's for adults.

make them pass a apple or orange from person to person without use of hands.
