Mac had a very old car. It was rusty and dirty, but its
engine worked most of the time. One day he took his old
car out of the garage and said to his wife, I'm going to
drive to Bournemouth and do some shopping.'
He came to a quiet road after a few kilometres, but then
his car stopped. Mac got out, opened the bonnet of the car
and looked at the engine, but he did not find anything
wrong with it.
His head was under the bonnet for quite a long time.
Then a young man ran to the car and began pulling one of
the red lights off the back of it.
Mac put his head up, looked at the young man and
shouted, 'What are you doing there?
The young man answered, 'You can steal the pieces at
the front. I'm going to take the ones at the back!
