An elderly woman went into the doctor's office.  When the doctor asked why
she was there, she replied, "I'd like to have some birth control pills."

Taken aback, the doctor thought for a minute and then said, "Excuse me,
Mrs. Smith, but you're 72 years old.  What possible use could you have for
birth control pills?"

The woman responded, "They help me sleep better."

The doctor thought some more and continued, "How in the world do birth
control pills help you to sleep?"

The woman said, "I put them in my granddaughter's orange juice every
morning and I sleep better at night."
