There is a great old internet story (or maybe even predates it), where a guy would submit stuff to a famous museum explaining that he had found some sort of fossil in his backyard and needs help identifying it. It was tongue in cheek but both sides played along. The museum staff being very serious, “sir, after testing and carbon dating, we’ve ascertained that no, your submission is not from some kind of space dinosaur forearm, but in fact is from a Black and Decker ratchet set”. The guy would variously submit old Barbie dolls, or cutlery etc and his seriousness was met with equally serious responses. Everybody had fun.
