Johnny's father said, "Johnny, we have a £200,000 mortgage on the house, and you want me to buy you a bicycle? Wait until Christmas."

Christmas came around, and Johnny asked again. The father said, "Well, the mortgage is still extremely high, sorry about that. Ask me again some other time."

Well, about two days later, the boy was seen walking out of the house with all his belongings in a suitcase. The father asked him why he was leaving. The boy said,"Yesterday I was walking past your room, and I heard you say that you were pulling out, and mummy said that you should wait because she was coming too, and DAMN if I'll get stuck with an £200,000 mortgage!"
