Sorry, I simply can't anymore, as per my previous reply. I've forgotten half the things I've written, and at this point, I wouldn't trust my brain to distinguish between stories from the letters or my conversation with David about them, and stories from Feynman's books.

I once spent a few days helping re-organize David Goodstein's files at Caltech. He was good friends with Feynman, so his files were full of their correspondence, which he did not mind me reading.

It's not even iTunes that's the problem - Canterbury Tales is drier than the Griswold's Christmas turkey.
