Have you ever heard of the Newlywed Game?
The gameshow pits newly married couples against other people who have just been married to prove who knows their partner the best. Some of the answers can get pretty hilarious, and it's funny to see couples struggle to answer the same way.
One very newly married couple played a version of this game at their wedding reception. Instead of competing against other couples, though, an announcer asked questions, and the pair had to raise either his shoe or hers in the air to say which one of them was most likely to be the answer.
