She wanted to buy the Zoo

A rich woman came to London one day. She had three children – two boys and girl. They ran and jumped and shouted all day. They never did what their mother wanted them to do.
When they were in London, the children said to their mother:
“Take us to the Zoo”. They look at the animals, and they had a nice time. They liked the Zoo. In the evening they said to their mother:
“You are rich. Buy the Zoo for us.”
“All right,” the mother said.
In the morning they all went to the Zoo again and the mother asked the Zoo people:
“How much does the Zoo cost? My children like it. I want to buy it for them”.
