For ten years, I've been obsessed with a single dialogue choice (really a collection of choices) at the beginning of Pillars of Eternity's first expansion, The White March: Part One.
Once you've finished beating back an ogre attack on the town of Stalwart, you're free to poke around, meet the residents, accept side quests, all that classic RPG jazz. At the docks, interacting with a suspicious barrel of fish reveals there's a man inside, and you can dump him out onto the street.
