A child, living in the inner city, goes on a school trip to see a
farm. When he gets back home, he discusses the visit with his father.

``So how was your trip, son?'' says the father.

``It was really good Dad. We went round and saw all the animals. First
we saw the goat, and it was really funny 'cos it had a big pointy
beard; and then we saw the chickens, and they were dead good 'cos they
were scratching in the ground and digging up worms; and then we saw a
field full of fuckers; and then we went to see the woolly sheep...''

``Hang on a minute,'' says the father, ``what was in that last
field?''

``What? The sheep?''

``No, the one before that.''

``Oh, the fuckers. Well, the teacher called them "heifers" but we knew
what he meant.''
