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," the doctor answered, "hemophilia is a genetic disorder and it is more often found in men, but it is possible for a woman to be a hemophiliac. Tell me, how much 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."
