Just when you think you have a problem fixed...

A woman goes to see her doctor and says:

Doctor, I keep on farting all the time... it doesnt smell or make sound at all when I break wind...
See... Since I've entered your office I might of break wind more than 50 times... and you havent even realised it...

The doctor listened carefully to her and hands her a prescription and wishes her a good day...

A week later, the woman comes back to see the doctor and says to him:

Doctor... I dont know what happend... but since I've been talking the medication, my farts have been so loud... I'm really embarrassed about it... it makes sooo much noise...

And the doctor hands her another prescription and says to her...

Now that we've fixed your hearing problem, lets fix your sense of smell...
