Carlin would have made a great high school history teacher. Most of them just kill any interest in the subject by drilling students on dry dates and lists of politicians. Carlin puts you right there.
I had a similar professor in college. Mrs. Stein, who must have been 65 or so. She taught history from a human angle, and made you feel like she must have been there. Maybe she had been.
One story of hers stuck with me. Her father, a professor at the University of Chicago, had worked on the Manhattan Project. After much pleading, he was granted a few days off to visit home, but was sternly instructed NOT to visit his old campus. They didn't want him discussing the project with any of his old colleagues. Well, he was walking one day at home and happened to pass by the campus. He thought about going inside, but then a man stepped out from around a wall and said, "Uh, uh, Professor. No visiting the school, remember?"
