If it's a young crowd, take the ladies out on the town! Make the bride-to-be a shirt that says "Free Candy With Kiss," attach candy to the shirt (individually wrapped lifesavers work great), and go bar-hopping!! For added fun, you can suggest that those who want her candy have to remove them from her shirt with their teeth
I've seen this done and it was freakin' hilarious! I am truly sad that I never had a bridal shower of my own...
