Dr. Kelso's nose is still bruised from Dr. Cox punching him a week ago, but no one will be a witness to the incident so Kelso can't punish him. But he can send him to the local prison to do physicals on the inmates. J.D. can't figure out what is wrong with his patient Mrs. Farr, so he goes to Dr. Cox for advice. Cox meanwhile, informs J.D. that he no longer will be available for consults now that he has new residents and interns to supervise.
