 The first class I had in geology, so you know what you're like, you know. So I went in and sat down, of course, in the back row, you know, one of those jerks. That's what I was, nevertheless, sitting in the back with another guy that was the same make that I was. And this fellow walks in and he's got a black coat on sort of thing, you know, that's a wrong name, but there's a name for the thing. And he's pacing up in front of the blackboard, back and forth, back and forth. So much so that the class just went dead in silence, you know, and you do right away he was playing the game with you, you know. But he, this was Dr. Warren, and he was a terrific teacher. And the first words out of his mouth, he looked at everybody's eyes and then he said, I want you all to learn to swim at this class. And everybody looked, and there was silence, and then he looked back and he said, we had two geologists paddling a canoe that drowned, and we don't ever want that to happen again. You know, God, just everybody was just dead on his eyes, and for a year they never took him off.
