And here's one from someone-who-shall-not-be-named
An American tourist goes on a trip to China. While in China he is very sexually promiscuous and does not use a condom all the time.
A week after arriving back home in the States, he wakes one morning to find his "tool" covered with bright green and purple freckles. Horrified, he immediately goes to see a doctor. The doctor, never having seen anything like it, orders some tests and tells the man to return in two days.
The man returns a couple of days and the doctor says "I've got bad news for you. You've contracted Mongolian VD. It's very rare and almost unheard of here. We know very little about it."
The man looks a little perplexed and says "Well, give me a shot or something and fix me up doc."
The doctor answers "I'm sorry, there's no known cure. We're going to have to amputate your "tool."
The man screams in horror "Absolutely not! I want a second opinion."
The doctor replies "Well, it's your choice. Go ahead if you want but surgery is your only choice."
The next day, the man seeks out a Chinese doctor, figuring that he'll know more about the disease. The Chinese doctor examines his tool and proclaims "Ah yes, Mongolian VD. Vely lare disease."
The guy says to the doctor "Yeah yeah, I already know that but what we can do? My American doctor wants to operate and amputate my tool!"
The Chinese doctor shakes his head and laughs "Stupid Amelican docta, always want to opelate. They make more money that way. No need to ampelate!"
"Oh Thank God!" the man replies.
"Yes," says the Chinese doctor. "You no worry! Wait two weeks. Dick fall off by itself! You save money."
