Miss Beatrice, the church organist, was in her nineties and had never been married, a sweet old lady...

... so the pastor was surprised to see, sitting on the keyboard, a condom.

She said, "I found it on the ground when I was walking through the park and it says it prevents the spread of disease if you put it on the organ, and do you know I haven't had the flu all winter?"
