Thanks for the link. Interesting that the audience in this video found this all to be quite amusing; however he was talking serious stuff here; So was the laughter because of a misunderstanding because audience and speaker? So maybe it doesn't quite sound so funny to me because in our age we are used to this kind of reasoning, and them back in the seventies weren't?
