Pin the Sperm on the Egg
You can find this hilarious baby shower game at pinthespermontheegg.com, amazon, etsy and ebay. Other products include invitations, balloons, word games and party favors. Created back in the late 1980's for a coed shower, this game started out as a handmade game by a stay at home mom. After many requests to make the game by hand, which was painstaking and expensive, she finally acquired trademark rights in 2003 and has been selling this ever since. It has been purchased for baby showers, fertilization celebrations, bachelorette parties and for a good-bye party for a retiring OBGYN!
