I can't find a good youtube clip of it, but Harry's iconic scene is definitely this one where he 1) explains that he probably told a courtier to go fuck himself but he can't really remember because the guy was just making him so mad, 2) he rants just barely out of earshot of the entire court about how much he hates the king and 3) keeps interrupting his uncle's attempts to tell him about an actual plot they're setting up against the king because he's just so mad, then 4) finally listens but immediately gets distracted imagining HOW AWESOME THIS WILL BE HE'S NOT AFRAID OF ANYTHING 5) no really really i'm seriously listening sorry
