Episode 15 of Family Guy season 13 (S13E15), the 246th Family Guy episode overall. Written by Anthony Blasucci and directed by Joseph Lee. First broadcast on 19 April 2015.
Story
Brian is put on medication, and while a dose is being forced on him he bites Peter on the arm. He is sent to obedience school as a punishment for the bite, and returns from it noticeably more submissive than he was before. A second storyline follows Chris, who strikes up a friendship with Neil Goldman. Chris works out in time that Neil has taken an interest in him only as a way of getting closer to Meg, and he is left unhappy about the whole arrangement.
