I was lucky enough to meet Irving Finkel a couple of times and he is as eccentric in person as he is in his brilliant lectures, talks, and videos. When I met him all the shelves, and even the floor, in his office was covered with different books, papers, and artifacts. He has amassed quite a collection of interesting things.
Here he is teaching how to write cuneiform: https://www.youtube.com/watch?v=XVmsfL5LG90
Here is a hilarious talk he gave at Chicago's Oriental Institute on Noah's Ark: https://www.youtube.com/watch?v=s_fkpZSnz2I
