Alas, there is no such thing (at least I don't think there is).
But...there is Twister. Yeah, you know, the game with the colored dots? And there are yogis to be found in every corner of the globe. So here's the recipe: add flexi yogi bodies of the male and female kind to one Twister game mat, throw in a couple cocktails, and I think there is a party in the making!
Seriously, a friend and I have been contemplating this for an upcoming soirée that will likely include many yogis. I mean, I can think of at least one person I'd like to play co-ed Twister with...can't you? While playing, there has to be potential for a Downward Dog, a Tree, an Eagle, at least? Tell you what...if we do break Twister out, I will be sure to get some photos and let you all know how it went.
