An elderly woman goes to her doctor and asks for birth control pills.
The doctor is shocked. "Why do you want those?"
She replies, "They help me sleep better."
The doctor is confused but thinks, Well, can't hurt, and prescribes them.
A couple of months later, the doctor sees the woman at the store and asks,
"So, how are those pills I gave you working?"
The old lady responds,
"Well, to tell the honest truth, they're fantastic. My beautiful 16-year-old granddaughter is living with me. Every morning, I put them in her orange juice, and I sleep at night like a baby."
