Carny Knowledge

While at the Quahog Fall Festival with their family and friends, Peter and Chris enter a "Generation Gap" contest together, but after many rounds, their team fails to win a single point, much to Lois' embarrassment. She orders Peter to get to know his son better, and they quickly bond over their shared annoyance at Lois' tendencies, as well as their love of mocking her. For a while, the two take pleasure in upstaging Lois at managing the household, namely by outvoting her ideas two to one. Taking advice from her friends, Lois decides to regain control by driving a wedge between Peter and Chris, faking essays and voicemails from both of them in order to induce a fight. However, they quickly catch on and swear revenge by threatening to destroy Lois' piano, but Lois admits that her plan was formulated solely out of her hurt feelings. As payback, Peter orders his wife to get a Mark Davis haircut in order to earn his forgiveness, which she resents.

Meanwhile, Brian meets a carny named Amber at one of the festival's booths and they immediately hit it off due to their shared love of hookups. He initially feels good about this relationship, as since she is leaving with the carnival in three days, he can get all the sex he wants out of her before she leaves. Despite the sex being amazing, however, Amber soon decides to call things off, much to his offense. Brian vows to get her back so he can be the one to break up with her, despite Stewie urging him to let it go. His plan almost works, before he is threatened into staying with her by her cruel uncle. While it is not shown what happens immediately after, Brian later comes home, only to be crushed by the raised piano from earlier.
