STAND BACK PEOPLE! Give me room, I'm about to make an analysis. After hours of careful scrutiny of the photos using such advanced methods as spectrum analysis, urinalysis, and photo synthesis, I have deduced that what you have there is...a rock.
I think the thing that confuses me is the weight of it. It feels like a piece of cast iron. It is soo small but weighs quite a bit. I dunno, may try it on ebay and just say it fell out of the sky during that metorid shower we had a few nights ago and it is autographed by elvis and dated July 02 2006
