And now for something completely different
Hello, good evening, and welcome to 'It's A Living'. The rules are very simple: each week we get a large fee; at the end of that week we get another large fee; if there's been no interruption at the end of the year we get a repeat fee which can be added on for tax purposes to the previous year or the following year if there's no new series.
Every contestant, in addition to getting a large fee is entitled to three drinks at the BBC or if the show is over, seven drinks - unless he is an MP, in which case he can have seven drinks before the show, or a bishop only three drinks in toto. The winners will receive an additional fee, a prize which they can flog back and a special fee for a guest appearance on 'Late Night Line Up'. Well, those are the rules, that's the game, we'll be back again same time next week. Till then. Bye-bye.
