Three men are sitting in the maternity ward. One is an Englishman, one a Welshman and the other a Jamaican.
Suddenly the doctor comes and says, "Gentlemen, your wives have all had little boys! However in the confusion we may have mixed the babies up. Could you come to the nursery to help us identify them?"
The Welshman ran to the nursery, picked up a dark-skinned baby and said, "This boy is mine."
The surprised doctor said, "But this child looks Jamaican."
"True," said the Welshman "but there is a fifty fifty chance that one of the others is English, and I'm not taking the risk."
