This elderly lady went to the doctor for a checkup. Everything checked out fine. The old lady pulled the doctor to the side and said, "Doctor, I haven't had sex for years now, and I was wondering how I can increase my husband's sex drive."
The doctor smiled and said, "Have you tried to give him Viagra?"
The lady frowned. "Doctor, I can't even get him to take aspirin when he has a headache," she claimed.
"Well," the doctor continued, "let me suggest something. Crush the Viagra into a powder. When you are giving him coffee, stir it into the coffee and serve it. He won't notice a thing."
The old lady was delighted. She left the doctor's office quickly.
Weeks later the old lady returned. She was frowning and the doctor asked her what was wrong. She shook her head.
"How did it go?" the doctor asked.
"Terribly, doctor, terribly."
"Did it not work?"
"Yes," the old lady said, "It worked. I did as you said and he got up and ripped his clothes off right then and there and we made mad love on the table. It was the best sex that I'd had in 25 years."
"Then what is the problem, ma'am?"
"Well," she said. "I can't ever show my face in McDonald's again."
