We were playing tag in the foundations of a burned out barn next to a pond. I tripped and tumbled off the foundation, falling 6' to the grass and landing flat on my back, breath knocked out, my friend, the "it" couldn't stop laughing, so he didn't jump down and get me, I got up and tried to run, kept falling down, he stopped laughing and said I was bleeding. . .turned out, a beaver had made off with a honeysuckle bush, leaving behind a nice sharp chisel shaped 1" diameter 3" long stump. . .which had stabbed me right in the middle of the back of my left thigh. T'was lucky it didn't hit a big vessel, nor did I land on it with my spine, neck or head. . . .one of my worst injuries, and I didn't even notice, no pain at all for 30 sec or so.
And yes, you might want to consider the possibility that it's a dice curse, I've had a few sets of totally non random dice over the years. (we used hammer in the driveway as our fix for those).
