"Lost all sense" joke

Lost All Sense
=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=
An elderly lady complains to the M. D. that she passes gas
many times a day.
"It's really more of a nuisance than a problem", she explains,
"they're silent and they don't smell."
The M. D. gives her a prescription and tells her to come back
in a week.
She returns and says,"I don't know what it was you gave me,
doc, but I still pass gas all the time, it is still silent, but it
smells terribly!"
The M. D. replies, "Now that we've cleared up your sinuses,
we'll see what we can do for your hearing."
