A woman is distressed because she has not been married very long, and yet her husband has lost interest in having sex. So, she goes to see her doctor, and relays the problem.
The doctor doesn't seem worried at all and tells her that this is nothing serious, that her husband has merely lost
his animal instincts.
The doctor tells her to crumble some dog biscuits on her husband's cereal every morning without telling him, and little by little this will bring out the savage beast in him.
He wishes her good luck and tells her to come back in a week with a progress report. A week later the woman returns to the doctor, who asks how her husband is.
"He's dead," she replies.
"Dead?" the doctor asked. "What happened?"
The woman replied, "He was sitting on the driveway licking his balls, and I backed over him with the car."
