I loved Lehrer growing up- my parents had his record "That Was the Week That Was" which I think is his finest work. Anyway, when I went to college (UCSC), I took his 'Nature of Math' course, which was quite enjoyable. He was a great presenter, I learned all sorts of neat stuff like the the quartic factoring challenge and the pigeonhole principle/birthday paradox (at the time, I didn't know much about hash tables and didn't make the connection). I almost ended up TA'ing his class the next year but I had to focus on my undergraduate thesis instead. I would have loved to get to know him better, as his sense of humor was incredible. I also had Ralph Abraham- a chaos theory guy and psychonaut who taught hist class (Nature of Math) in a natural amphitheater- at points, I could almost picture him wearing a toga, lecturing us on greek math.
