John treats a man who displays three distinctive personalities, all of whom drive John crazy. At the diner, Chris and Jake annoy each other with their irksome habits, and Bob becomes a big brother to a 10-year-old boy.

Jake begins to believe his blindness makes him less of a person after he allows a thief to walk right past him with cash stolen from the diner. Chris and John's attempts to cheer him have the reverse effect, so John takes Jake to a hockey game to take his mind off of the matter. But Jake thinks he hears the robber's voice at the game and wants John to make a citizen's arrest. At John's office, Margaret is hit on by a smooth-talking salesman.
