This elderly couple is shuffling their way past some other old folks in their favorite pew at church one Sunday morning. When they finally hit an open spot they start to sit down when suddenly, the old lady feels a fart slip out just before her butt hits the seat. She turns to her husband and whispers, "Oh no! I just had some gas slip out of me. Thank God it was a silent one. What do you think we ought to do?" The old man slowly leans over and whispers back, "Well Honey, first thing we gotta do is change the batteries in your hearing aids."
