Animal Instinct

A woman was very distressed because she has not been married very long and yet her husband has lost interest in sex. So she went to see her doctor and relayed the problem.
The doctor didn’t seem worried at all and told her that it was nothing serious and that her husband had merely lost his animal instincts. The doctor told her to crumble some dog biscuits on her husband’s cereal every morning without telling him, and little by little, this would bring out the savage beast in him. He wished her good luck and told her to come back in a week with a progress report.
A week later, the woman returned to the doctor, who asked how her husband was.
“He’s dead,” she replied.
“Dead?” the doctor asked.
“Yes. He was sitting in the driveway licking his balls, and I backed over him with the car.”
