This doctor goes to see a psychiatrist. He says, “I’ve been having an affair with one of my patients for months. I just can’t give her up and the guilt is really getting to me.”

The psychiatrist says, “As long as neither of you are married, it isn’t really that big of a deal. It’s a common temptation that we all have faced. You shouldn’t continue to see her as a patient, however. What’s your specialty?”

The guy replies, “Veterinarian”.
