A doctor that had been seeing an 80-year-old woman for most of her life finally retired. At her next checkup, the new doctor told her to bring a list of all the medicines that had been prescribed for her. As the doctor was 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 and 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."
