my SIL had a great game, at my bridal shower...
there were three gift bags, each one full of various candies (Snickers, Big Hunk, Rocky Road, Abba Zabbas, Milky Way, etc.) and a stick of glue. she had everyone divide up into 3 groups, and each group got a poster board - one was "The First Date," the second was "The Wedding Night," and the third was "10 Year Anniversary"
each group had to write out a story, or advice, using as many of the candy bars/packets as possible, and then when they were all done, each group read it aloud.
dh's grandma turned bright red.

it was a little risque, but nothing bad. it was DEFINITELY funny!
