Continuity mistake: The scene where the elementary school teacher asks his kid what they did that week. After he asks that question and Maizy raises her hand, look at the desk belonging to the girl in the row next to Maizy. It has crayons and other supplies on it. After the teacher calls Maizy's name, the shot goes back to her, showing the girl in the next row's desk completely empty. (00:58:00)
Chosen answer: He's being sarcastic, as Buck says in the beginning some of his hats anger a lot of people, which probably connects to when his hat gets taken by one of the teenagers at the party.
Buck is actually referring to his aviator style hat in the earlier scene about people being angered by it. He's wearing the fedora style hat in the scene en route to the party. But I agree the guy was being sarcastic about teenagers.
