The Ladybird Guide to Leftwing People. From the chapter Leftwing People Are Funny:
Leftwing people have “enlightened comedians” who make jokes on “panel games.” These are broadcast on the television and BBC Radio 4. The enlightened comedians make people laugh at rightwing people, whom they consider stupid. In the olden days, comedians made jokes about Irish people, but these comedians weren’t clever like the enlightened comedians.
Instead of the Irish people, the enlightened comedians make jokes about working-class people. Because they care, they use special words like “Glaswegians,” “Sun readers” and “UKIP supporters,” so the working-class people will not notice.
Working-class people do funny things like drinking Monster energy drinks, eating Haribos and watching television. This is funny and the enlightened comedians are helpful because they point at them and laugh, so we know who to laugh at as well. It is very funny and we all laugh because we are enlightened too.
