Western Doctors 

One day this bloke travels to the Far East on business. He goes to many countries with great success but 3 months later arrives home to find he's contracted a strange disease in the genital region. The doctor gives him the news that his penis has to be amputated.
"But this is terrible, I just cannot accept it. I will consult another physician."
So the bloke sees numerous doctors all over Europe and North America but they all come to the same conclusion. His member has got to be chopped off. Just as the plane's landing at Heathrow the bloke has an idea. If it's an Oriental, Far-Eastern disease then why doesn't he consult an Oriental doctor! So an appointment is made and it's off to Chinatown in London. The bloke explains his problems and the doctor gives a full examination.
"No, I don't think amputation is necessary", says the oriental doctor. The patient is over the moon.
"Brilliant! I saw dozens of doctors from Europe and America. They all said amputation was the only way."
"Pah!! Western doctors", says the Chinese gentleman with disdain. "What do THEY know !?!. Any doctor worth his salt could tell you that it'll drop off by itself in 4-6 weeks!"
