I've played the "strip poker" before and it's great fun.
I've also participated in a "Chinese fabric exchange". Each person brings a yard of some gorgeous fabric, wrapped or in a gift bag. We bring our chairs into a big circle and put all the packages in the middle. We all draw numbers, then in number order each person can either choose a package or "steal" a fabric you like from another person. If your fabric is stolen, you get to either choose another package or steal from yet another person, and so on. When everyone has had a turn, the person who had Number 1 gets one last chance to trade her fabric with someone else. We usually allow a fabric to be "stolen" only three times and then it's frozen, or else the game could go on forever. It's a lot of fun and we have a great time trying to hide the fabric so it won't be stolen.
