Another year older

A great joke in honor of my birthday.

“My wife and I were recently attending a church service.
About halfway through the service, I took a pen and paper and wrote a note
and handed it to my wife.

The note said:” I just let out a silent fart, what do you think I should do?”

My wife scribbled back: “Put new batteries in your hearing aid. ”
