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 to you lose when you have your period?" 

 

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