Here goes...
This elderly lady goes to see her GP with a most embnarrasing problem.
"Doctor. I have terrible flatulence. No matter what I seem to eat and drink, I constantly have wind. Thank god, it doesnt make much noise, nor smell particularly but it is most embarrasing. Is there anything you can do?"
Without really listening to her, the doctor proceeds to write something on a perscription form, which he then hands her.
"Take one of these tablets, twice a day with meals, for a fortnight and come back to see me."
So, a fortnight passes, and the elderly lady returns, deeply upset.
"Doctor, I'm afraid things are now much worse! In the last fortnight, I've been just as flatulent, only this time, thanks to these tablets, they have been really odourus. It's most embarrasing, I have hardly dare leave the house! Please, Doctor, is there anything else you can do? I don't feel these are helping."
Raising his voice slightly, "Well now, Mrs Johnson. Now we've fixed your olefactory troubles, lets see what we can do for your hearing, shall we?"
:-P
