The most surprising thing of all is that some family members had never even heard of such a thing. How can that be? Is our family hiding our talents under a bushel instead of sharing them with the world? What a shockingly selfish thing to do.
Another common family talent, but, sadly, one I don't possess, is being able to wiggle your ears. Maybe we just like to do weird things with our faces. When Dad was in Kindergarten his teacher thought he had a deformed ear because when he got nervous he would tuck the outer ear into the inner ear, and it would stay there.
