The trouble with/for people who wear wigs is once you start you can't stop. Because wearing one is a lie, and to stop you have to admit to lying, and to being bald, and to being the sort of person thats so worried about being bald that they'd wear a wig and lie about it. And of course theres the point where everyone knows you are wearing a wig, but you keep on wearing it so you are lying even though everyone knows its a lie.
Paul Daniels was the funniest, he started wearing a wig because he was worried about going bald, but didn't want to be seen to go bald before he started wearing one. So he started to wear one while he had a full head of hair. Then didn't go bald. Then he stopped wearing it (by the time spitting image were making fun of his wig he'd stopped wearing it but the press hadn't noticed). Then he went bald.
