I happened across an ostensible letter to the Smithsonian today that begins thusly:
Dear Sir:
Thank you for your latest submission to the Institute, labeled “211-D, layer seven, next to the clothesline post. Hominid skull.” We have given this specimen a careful and detailed examination, and regret to inform you that we disagree with your theory that it represents “conclusive proof of the presence of Early Man in Charleston County two million years ago.” Rather, it appears that what you have found is the head of a Barbie doll, of the variety one of our staff, who has small children, believes to be the “Malibu Barbie”.
It goes on for a bit and it’s quite funny. It’s also 100% untrue.
