Doctor Roy had just finished a marathon sex session with one of

his patients. He was resting afterwards and was feeling a bit guilty

because he thought it wasn't really ethical to screw one of his

patients.

However, a little voice in his head said "Lots of other doctors

have sex with their patients so its not like you're the first...". This

made Dr. Roy feel a little bit better until still another voice in his

head said, "... but they probably weren't veterinarians".
