K.W.
The last shower I gave I bought about 15 pairs of socks differnt patterns in all different baby sizes. I put them in a cute decorated basket and the goal was to see how many pairs of socks each guest could match in 10 seconds. Then the mom-to-be got to keep the socks as part of my gift to her.
Another one is matching baby food. Buy about 10 jars of baby food, tear off the labels, number the lids 1 thru 10, and have the guests guess what each food is. They are allowed to smell and tip-of-finger taste if they want to. The best thing is that there are so many different things out, like beef and gravy, the popular hawaiian delight, blueberry cobbler. If you mix it up with those, then it is a lot more fun then just peas and carrotts.
