Been There, Done That
Sit everyone around in a circle and hand out a notecard and a pen to all of the girls. Ask them to write down an embarrassing moment they have had on a date.
Once everyone has written down all their stories, hand them back to the Bride who had to read them out and guess who wrote it. You will be roaring with laughter.
What you need:
*Notecard - one for everyone in the group
*Pens - one for everyone in the group
