Humour is an important aspect of life in Britain. British people can laugh and make
jokes in almost any everyday situation. A lot of people consider that a '_ is more
important in a partner than good looks or money. Britain's comedy industry is huge.
with a large number of TV comedy programmes and comedy festivals. The nation's top
are superstars who perform live shows all over the country in front of thousands
of fans. So why are humour and comedy particularly important in Britain? It's well
known that is good for you. When you laugh, your body releases hormones which
make you feel happier, healthier and more optimistic about life. Sunshine has a similar
effect, so maybe the British need laughter because the weather is so bad.
Unlike film actors and musicians, Britain's comedians and TV comedy
shows generally aren't very popular in other countries. Of course, every nation has its
own sense of humour, but the British sense of humour seems to be particularly difficult
to understand if you aren't British. The British often use *_-for example, they might
say 'Well done!' when someone makes a mistake. British comedy characters are often
very unkind and rude to each other and British people love to s_themselves, too. For
people from other cultures, this can all seem negative, embarrassing or offensive.
However, not all British humour is incomprehensible to people outside the UK. The Mr
Bean TV shows and films, for example, have been popular in over 200 countries over
the last twenty years. Mr Bean is funny because he does simple, everyday things in
an extremely _ absurd way. People laugh at Mr Bean, but they also appreciate his
eccentric behaviour. Loving eccentricity is another important side to the British sense
of humour and maybe one that they share with people around the world
