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."  You gotta love Grandmas!
