The man and his wife went to the doctor for their annual physical exams.
Afterwards, the doctor called her into his office and told her that he had some good news and some bad news. "The good news," he explained, "is that your husband has a particular strain of gonorrhea that I have only heard of once before."
The wife paled. "If that's the good news, then what the hell is the bad news?"
"Well," the doctor elaborated, "the bad news is that I heard about it just last week from my sheep's vet."
