An eight-year-old boy went into the corner shop and picked out a large box 
of
washing powder. The shopkeeper asked him if he had a lot of washing to
do. "Oh, no," the boy said, "I'm going to wash my dog."
"But you shouldn't use this to wash your dog," said the shopkeeper.
"It's very powerful and if you wash your dog in this, he'll be ill.
In fact, it might even kill him." But the boy was not to be stopped
and carried the washing powder to the counter and paid for it.

A week later, the boy was back in the store to buy some sweets. The
shopkeeper asked the boy how his dog was doing. "Oh, he died," the boy
said. The shopkeeper said he was sorry, but added,
"I tried to tell you not to use that detergent on your dog."
"Well, the boy replied, "I don't think it was the washing powder that
killed him."
"Oh? What was it then?"

"I think it was the spin cycle!"
