If you have or can make the supplies, and are a little creative, you can make a simple bingo game. Anything small and round - from traditional bingo chips to Cheez-Its can be use for markers. If the names (his, hers, etc) aren't too long, it shouldn't bee hard.
Also, Charades, and Pictionary type games can be fun, especially if men compete against women. Just remember to keep it friendly and clean, lol! But I know you will.
Oh! I just threw one in October! I did a crossword puzzle featuring questions about the couple, a multiple choice "how well do you know" this couple type of questions, a name game "her married name will be..." and people had to make words out of the letters (this was timed & people loved it!). Buy some measuring spoon sets and make up a poem about love being immeasurable or something like that. I can't give all my secrets away. I have another one to throw! Good luck & have fun!
I like LoriW's idea, see what men know about women things and vice versa. Should be interesting!
How about pitting the men against the women to play trivia similar to Battle of the Sexes? You ask the men questions that women would know (like about cosmetics, fashion, etc.) and the women questions that men would know (like about cars, sports, etc.)
