Young blonde lady goes to see the doctor. She tells the doctor " You wont believe this, but I can pass gas all day long, and it is silent, and has no smell". The doctor dubious at the claim, said "I see, how long has this been going on?' The blonde replied that it had gone on for about a week. She added "Doctor I don't think you believe me, but I will have you know that I have passed gas nearly 30 times since I have been in here. The gas is silent, and doesn't smell" . The doctor gave her a prescription and asked that she return in two weeks.
The blonde returned highly upset, and said "Doctor what did you give me , when I was here? My gas passing is still silent, but because of those pills my gas smells terribly".
The doctor replied...."Good , now that we have your sinuses cleared up, let's working on your hearing."
