An elderly woman goes to the doctor and asks his help to revive her
husband's sex drive.

"What about trying Viagra?" asks the doctor.

"Not a chance," says Mrs. Murphy.
"He won't even take an aspirin for a headache."

"No problem," replies the doctor. "Drop it into his
coffee, he won't even taste it. Try it and come back
in a week to let me know how you got on."

A week later Mrs. Murphy returns to the doctor and he inquires as to how
things went.

"Oh it was terrible, just terrible doctor."

"What happened?" asks the doctor.

"Well I did as you advised and slipped it in his coffee. The effect was
immediate. He jumped straight up, swept the cutlery off the table, at
the same time ripping my clothes off and then proceeded to make
passionate love to me on the tabletop. It was terrible."

"What was terrible?" said the doctor, "was the sex not good?"

"Oh no doctor, the sex was the best I've had in 25 years, but I'll never
be able to show my face in McDonald's again."
