A TV programme which I watch now and then is named 'Mysteries at the Museum (or its variant ...at the Monument')and I hope all we contributors to this thread will watch it. and hurl abuse at the presenters for their misuse of language. Some of them think a skeleton is an artifact. None of them seem to use the term 'exhibit.'
