Harry wanted a new suit so he bought a nice piece of cloth and tried to find a good tailor.
The first tailor he visited looked at the cloth, measured Harry, then told him there was not enough cloth to make a suit.
Harry found this hard to accept, so he went to the tailor next door who measured both Harry and the cloth before announcing that there was enough cloth to make a three-pice suit.
A week later, Harry returned to collect his suit and noticed that the tailor’s son was wearing trousers made of the same cloth.
Puzzled, Harry asked: “How come you have been able to make a three-piece suit for me and trousers for your son when the chap next door could not even make a suit?”
“Simple,” said the tailor. “The guy next door has two sons.”
