A streetwalker was visiting her doctor for a regular checkup.
"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 hemophiliac?"
"Well, hemophilia is a genetic disorder, and it's most often found in men," answered the doctor. "But, some woman do get hemophilia. Tell me, how much do you lose when you have your period?"
After some quick calculating, the hooker replied, "Oh, about seven or eight hundred dollars, I guess."
