I like that

A Turk, father of 8 children, decides to go to Germany to earn enough money to build a house for his family. When he comes back after four years, he finds his children have grown up - but there is a small new baby. Angry he asks his wife how it happened that she gave birth to a child while he was far away. She said: "My husband, while you were abroad I missed you very much, and every evening I looked at your picture before I slept. So I became pregnant." Her husband is satisfied by her answer. His children grow up, and the ninth one becomes a handsome young man. Suddenly, the Turk asks his wife to show him the picture. "What picture?" his wife says. "Well, the picture you were looking at when I was in Germany!". His wife digs into the remotest places of her truncs, and finally shows him the old passport-sized photograph he gave her before he left abroad. The turk lengthly looks at the photo, and suddenly becomes red from anger. "My wife, you cheated me, on this picture you see only the upper part of my body. How is it possible that you became pregnant looking at it?"
