"The crystal glass bowl" joke
Sister Mary Holycard was in her 60s, and much admired for her sweetness and kindness to all.
One afternoon early in the spring a young priest came to chat, so she welcomed him into her Victorian parlor.
She then invited him to have a seat while she prepared a little tea.
As he sat facing her old pump organ, the young priest noticed a crystal glass bowl sitting on top of it filled with water, and in the water floated, a condom.
Well, imagine how shocked and surprised he was. Imagine his curiosity! Surely, he thought, Sister Mary had flipped or something!
When she returned with tea and cookies, they began to chat, and of course, the priest tried to stifle his curiosity about the bowl of water, and the strange floater. Soon it got the better of him and he could resist no longer.
"Sister," he asked, "I wonder if you could tell me about this?" (pointing to the crystal bowl)
"Oh, yes," she replied, "Isn't it wonderful?"
"I was walking downtown last fall and I found this little package. The directions said to put it on the organ, keep it wet, and it would prevent disease. And you know I haven't had a cold all winter!"
