An eldery woman goes to the doctor for a most embarassing problem. After a short wait in the exam room, the Doctor comes in, and she tells him her problem.
"Doctor, this is so embarassing, but I don't know what else to do. For over a month now I have been passing wind almost continuoulsy, and although they are silent, and have no odor, I am so afraid that one will slip out that people will be able to tell. I have passed wind at least ten times just while waiting for you in this room."
The Doctor smiles and says, "Thats quite alright Mrs. Smith, no need to be embarassed with me. I have just the thing to help you."
The Doctor writes a prescription for her and asks to see her next week.
When she returns the following week, she is quite upset. When the Doctor comes in the room she says, "Doctor, I don't know what you gave me, but I am still passing just as much wind, and although they are still silent, they smell absolutley rotten!"
The Doctor smiles and says, "Well great Mrs. Smith, now that we have your sinuses cleared up, we can work on that wind problem."
