OK, well anyway, one day many years later, he called up and we were talking about the... the AI movie, and... but I asked him what else he was doing and he said: 'Well I'm just... I’ve just been very worried about the world political situation,' and he said: 'Do you know that the Americans and Russians agreed to cut the number of atomic bombs from 40,000 to 20,000 recently?' And... and he said: 'This is really pathetic because it can’t really make any differences as long as they all have enough to destroy the world and...'  He said: 'I wish... can’t anybody get through to them to realize they’ve got to... do something much more effective than that?' And there was a long silence and then I said: 'Well, many years ago you made that movie called Dr Strangelove, which explained that just more clearly than anybody could possibly do, and if that doesn’t work, I don't know what would. There was another long silence and he said: 'Oh, I forgot about that.' I just... I just love this true story because it had these two long silences.
