Gosh, there are so many of y'all that I'd like to have dinner with - I'm gonna skip that. There would be enough for breakfast, lunch and dinner, and plenty left over for a nightcap.
But as for The Famous Smokers:
General George S Patton, Jr. - One of my greatest heroes, and from all reports a warm, engaging individual.
John Ronald Reuel Tolkien - Just to hear the stories.
Clive Staples Lewis - He would have to be seated away from Tolkien, though, so I could get his viewpoint on a couple of matters.
Graham Chapman - He and Tolkien would be great conversation, but Chapman and Lewis would have little in common.
Who is not invited:
MacArthur, since he was a gold-plated SOB, and Lincoln, because of that whole War of Northern Aggression, and Stalin, because a million deaths is a statistic. Those are the only pipesmokers that I probably couldn't get along with.
