Grandma's logic....

The 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 young
doctor was looking through these, his eyes grew wide as he realized she 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. "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 helps me sleep at night."

You gotta like Grandmas
