A middle-aged woman seemed sheepish as she visited her gynecologist.
"Come now," the doctor coaxed, "you've been seeing me for years!
There's nothing you can't tell me."

"This one's kind of strange..."

"Let me be the judge of that," the doctor replied.

"Well," she said, "yesterday I went to the bathroom in the morning and I
heard a plink-plink in the toilet; when I looked down,
the water was full of pennies."

"I see."

"That afternoon I went again and there were nickels in the bowl."

"Uh-huh."

"That night," she went on, "there were dimes and this morning there
were quarters!  You've got to tell me what's wrong with me!" she
implored.  "I'm scared out of my wits!"

The gynecologist put a comforting hand on her shoulder.
"There, there, it's nothing to be scared about.  You're simply going
through the change!"
