In high school I had a very eccentric, British, social studies teacher that traveled the world every chance he got. He owned a vast collection of slides that he had taken everywhere he went. Every class consisted of a lecture about one of his adventures accompanied by a fabulous slide show!
When I see the cartoon character Nigel Thornberry I am very much reminded of him.
Except that my teacher also had very large and puffy sideburns. LOL
