Once in a conference, three scientist. A Chinese, a German and a Tanzanian, were talking and bragging about the technological advances their representative countries have achieved in the field of medicine. Says the Chinese, "In Guizhou (Kweichow), there was a baby boy born without forearms, so we attached artificial forearms on him. And now that he is grown, he has become an Olympic professional Martial Art and a gold medallist at that." The German replied, "That's nothing to what we have done back in Berlin, there was a baby girl born without legs on her, she is 3 times marathon gold medallist in the Olympics!" The Tanzanian interjected laughingly, "Is that all you have, just gold medallist? In Dar es Salaam, we have a baby born without a head! We attached a coconut to the neck and he is now the president."
