John gets upset when a patient refuses to take any more medication because he believes God is healing him through prayer. At the diner, Bob brags that he is part Native American and tries to cash in on his newfound heritage, and Linda attempts to keep up the charade in her "long-distance" relationship with a fellow New Yorker.

John feels like climbing the walls after Chris bans smoking from the diner and Margaret won't let him light up in the office. Elsewhere, Bob convinces Jake that Amanda is cheating on him after Jake unwittingly walks into the diner wearing lime green pants that are too small for him; and Linda persuades John to treat a friend's dog.
