Bills or change?

This lady goes to the gynecologist but won't tell the receptionist what's wrong with her, just that she must see a doctor. After hours of waiting the doctor sees her in. Ok my good woman what is your problem the doctor asks. Well, she says, my husband is a very compulsive gambler and every nickel he can get his hands on he gambles. So I had five hundred dollars and I stuffed it in my vagina but now I can't get it out. The doctor says, don't be nervous I see this happen all the time. He asks her to pull down her underwear sits her down with her legs wide open puts his gloves on and says: I only have one question. What am I looking for? Bills or loose change?
