Birth control in an African Village

The great white doctor comes to an impoverished African village where he sees several young mothers either pregnant or with several small kids in tow, all showing signs of malnourishment. On inquiry through an interpreter, he learned that the chief was a rather amorous character and all the ladies and children belonged to him. So he sent a large box of condoms to the chief with instructions to always use it. A year later, he returns to the same village only to find the chief's wives still pregnant or with new born children. Annoyed, he sends for the chief and, through the interpreter, demands an explanation. The interpreter listens to the stammering chief and explains, " But doctor, he swears he always wore the condom." "Then how the heck did this happen?" The interpreter questions the chief, listens, and replies, "He says after three days he desperately needed to pee and so he made a small hole at the tip."
