To accuse teachers in England who have complained to the Advertising Standards Authority of having a sense of humour bypass is to miss the point. A thorough investigation could be highly entertaining. Should Londoners also troop along behind them, parading their resentment against the suggestion from north of the border that their city is anything other than a splendid place in which to teach?
Of course, all the wiles of the marketing trade have to be deployed to win new recruits and their efforts might even be understood on occasion. The best adverts for teaching, however, are teachers themselves. The more unions talk down the job, the more people might be content to reach for the anti-wrinkle cream - if it works.
