All Men Baby Shower
Host a baby shower just for the men. You can turn it into a Poker tournament and the price to get in is a package of diapers (size 1 or 2). Make sure you don’t have all the guests bring newborn diapers, since babies outgrow them quickly. Then the winner gets cash or a gift certificate to a restaurant, Home Depot or where ever.
You won’t need to come up with any other games or decorations. All you will need is some poker chips, cards and snack food.
