Names and faces again

Watching an old episode of Blake's 7 this morning, I was wondering who that familiar-looking actor was. It took me a while to penetrate the clean-shaven young face, sideburns and late-seventies hairstyle, before his voice made me realise "Oh, it's Inspector Grim! David Haig!" And then immediately after that revelation I got an email from David Haigh, no relation, which just makes me think that things would be a lot simpler all round if everybody had the same name. So from now on, everybody has to be called David Haig(h), okay? You can choose whether or not to put an H on the end. I'm sure this will improve world understanding and harmony immeasurably.
