George swore that if he was ever going to consider doing another cameo it would involve sitting in a chair, preferably with a large drink in hand. The life of an extra, standing hours in costume during dozens of takes was not high on his list!
One bit I found amusing was talking about creating names for writing. George first did a brief rundown on English names during the middle ages. Essentially a few simple names dominate. If your name wasn't Henry, Edward, or possibly Richard, you weren't going down in the history books. Then he talked about hearing interesting names and keeping those for future stories. He said when watching the NFL draft each year he picks up a couple of neat names for future use. Now I won't be surprised when Ser Ochocinco pops up in book 7...
