A young couple went to the doctor for their annual physical exam.
Afterwards, the doctor called the young man into his office and told him that he had some good news and some bad news.
"The good news," he explained, "is that your fiancee has a particular strain of gonorrhea that I have only heard of once before."
The guy was appalled.
"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 this nasty strain just last week from my dog's vet."
