I have only heard of this one:
Get a bunch of the 4 oz gerber juices and gerber bottle nipples/rings and make mini-bottles - guests have to drink them - first to finish gets a prize!
This one was done at my baby shower - buy a piggy bank and have guests bring their pocket change in exactly 8 coins - you go around the room, passing the pig - the person who starts says "have you ever..." and names something they have done/someone they met/place they've been that they think no one else has done - the pig gets passed and each person who "hasn't" puts a coin in - the pig stops at the person before the one who started it and they start the next round - go until people run out - last to run out of coins wins a prize! Oh and the pig and the money goes to the baby!
