A streetwalker was visiting her doctor for a regular check-up. "Any 
specific problems you should tell me about?" the doctor asked.

"Well, I have noticed lately that if I get even the tiniest cut, it seems
to 
bleed for hours," she replied. "Do you think I might be a
haemophiliac?"

"Well," the doctor answered, "haemophilia is a genetic disorder and it is
more often found in men, but it is possible for a woman to be a 
haemophiliac. Tell me, how much do you lose when you have your 
period?" the doctor inquired.

After calculating for a moment the hooker replied, "Oh, about seven or 
eight hundred dollars, I guess."
