Caveman Re-Enactors

See, we should totally start a caveman reenactment group.
There are ample resources - anthropological bones and re-creations, archeological digs, not to mention the Flintstones! And there's Ug, the Caveman Musical, Clash of the Cavemen, Journey to 10,000 B.C., Caveman Toys, Walking with Cavemen, Cavemen, The Paleos and Cavemen of NYC, not to mention books like Jean Auel's Earth's Children series.
I think the time is right to start a caveman reenactment group. We could dress in furs, sing around campfires, play hunter/gatherer games, and make pottery and baskets and such.
