Needed: Pencil/pen and paper for each player.
Directions: Call off the items. If the player has that item in her purse then she adds the points to her total. The one with the most points wins.
Note: Here are some ideas of items someone may have in their purse. You can cater the items to the crowd. If there are more ladies without kids then have less mom-orientated items etc.

Rosary
Photo of your kids
Key chain with a religious theme
Receipt for baby supplies (diapers, clothes, etc)
Prayer card
Tissue pack
Photo of your husband
Church Missal
Calendar/Planner (paper or electric) with the baby shower date scheduled
Something with a bible scripture on it.
Binky/pacifier
Brush or comb
Kiddie snack (ie. cheerios, fishy crackers)
Appointment card or receipt for a mani/pedi
Church bulletin
Mini screwdriver, scissors or pocket knife
Five or more keys on your key chain
Thanks to Katie S. for the idea!
