A few years ago, MrsC and I went to a weekend about Stonehenge at a local adult education centre.
There was a pomposity present, including Mike Parker Pearson.
The custom of that centre is for the Friday night session to be slightly off-topic or at least less serious, so they'd got the assistant county archeologist in to do a talk on some rescue archeology schemes. Poor chap looked terrified lecturing to that lot.
(Also there, but not a professor, was Julian Richards from Meet the Ancestors--amongst other things. We ended up having tea and cake with him and he seems to be a really nice chap).
