I'm sure I got this idea from Family Fun magazine. (the greatest magazine I've ever subscribed)
Get an empty gift bag.
Fill it with something from around the house.
Give it to someone who is playing the game.
The recipient must say "Thank you!" immediately, then open the present and say one nice thing about whatever is in there.
I like this "game" because it's practise for the real world.
The funniest present from Kaylee was a potato head ear. I said, "Thank you! I love that color pink" and then laughed for a very long time.
