BRIDAL SHOWERS: Assemble a dozen or so photographs of the bride, showing her at different ages. Mix them up so they're not in order. Give pencils and paper to everyone, pass the photos around or display them someplace where everyone can see, and have guests write down their guess as to how old the bride was in the picture (she has braces, so that must have been in junior high). A prize goes to the person who gets the most ages right.
This is the kind of bachelorette game I am OK with. [Everyone attending should bring a pair of (BRAND NEW) panties that ‘represents’ them or would somehow remind the bride of them. For example, someone who loves cats can bring a Hello, Kitty! thong. Then, you lay out all the panties and the bride must guess which panties belong to each guest. The bride gets to keep all the underwear as a souvenir.
