Ron winning his bet against Jack Lime that he'd receive higher viewer figures despite having an awful news slot, just by (in a rare moment of cunning) giving the US public the sort of news they'd like to hear. The moment when Jack first has to call himself "Jack Lame" is sweet, sweet victory.
Brick standing up to his girlfriend's boss when she mistreats her.
Brian and Champ standing up for Brick after Ron yells at him. Despite struggling to say something badass, Brian saves the moment by knocking Ron to the ground, before leaving with Champ and Brick.
The climactic news brawl is this in addition to being ungodly hilarious.
