Do some kind of trivia game that pits husband against wife or pair people up. Maybe do a family trivia. Put together questions about peoples lives and split the group up into 2 teams and pit one member of each team against the other. E.g. This person learned in x yeshivah or bais yaakov. Who is it? Should be lots of fun.
