farting issue

I went to the doctor and said,

“Doctor I have this problem with gas, but it really doesn’t bother me
too much. It never smells and is always silent. As a matter of fact
I’ve farted at least 10 times since I’ve been here in your office. You
didn’t know I was farting because it doesn’t smell and is silent.”

The doctor says to me,
“I see. Take these pills and come back to see me next week”.

The next week I return to the doctor..
“Doctor,” I say, “I don’t know what the heck you gave me, but now my
farts, although still silent, stink terribly”.

“Good,” the doctor said. “Now that we’ve cleared up your sinuses, let’s
work on your hearing.”
