ok so i just got this e-mail about this fart joke and thought it was pretty good. so here:
An elderly couple was attending Mass. About halfway through, the wife leans over and says to her husband, 'I just let out a silent fart. What do you think I should do?" He replies, "Put a new battery in your hearing aid."
