"One of my favorite episodes in West Wing was the homeless man that died and they found, in the overcoat he was wearing, a card of the speechwriter, Toby. He had given that coat to the Goodwill and this guy had ended up wearing it, died in it and Toby went to his funeral. He turned out to be a Korean war veteran. It was our first Christmas episode and that was a true story - a member of the staff had done exactly that. So many of these stories were far better than any fiction."
