Hang Them Out To Dry
Each guest is given a clothespin upon her arrival to the shower. She is told of two words she cannot mention (i.e. "wedding", and the groom's name). If she says those words during the party, she loses her clothespin(s) to the one who caught her. The person who has the most clothespins at the end of the day wins the prize.
