A doctor who had been seeing an 80-year-old woman for most of her life finally retired. At her next check-up, the new young doctor told her to bring a list of all the medicines that had been prescribed for her.. Looking through these, his eyes grew wide as he realized Grandma had a prescription for birth control pills.

"Mrs. Smith, do you realize these are birth control pills?"

"Yes, they help me sleep at night."

"Mrs. Smith, I assure you - there is absolutely nothing in these that could possibly help you sleep!"

She reached out, patted the young doctor's knee and said, "Yes, dear, I know that. But every morning, I grind one up and mix it in the glass of orange juice that my 16-year-old granddaughter drinks. And believe me, it definitely helps me sleep at night"
