Some Like it Hot - Pretty good interview with Alton Brown, the “Good Eats” guy:
I can't talk about anything or write about anything if I don't understand it. So a lot of the stuff that I go through and a lot of the time that I spend is understanding. Because I flunked all my science classes in high school and I flunked most of my science classes in college, so I came out of school almost completely devoid of scientific knowledge.
