A Doctor goes to a psychologist.... And tells him he is feeling very guilty about sleeping with one of his patients. He is having a hard time going back to work because he thinks all of his co workers know. The psychologist said there's nothing to be ashamed of because humans can't always control urges and even he has slept with a patient. After a few sessions the Doctor finally feels relieved about his incident. The psychologist asked what field of medicine the doctor practiced. ""Oh I'm a veterinarian"", said the Doctor.
