Context: The Warhammer 40,000: Black Crusade introductory adventure “Broken Chains.” New GM and all new players.
GM: [paraphrasing] You are in a circular prison cell with a thick steel door and an air vent.
Chaos Marine: I force open the door.
GM: Even your augmented might cannot match the magnetically sealed lock. You fail to open the door.
Chaos Marine: I sulk in the corner.
GM: You’re in a round room, so you fail at that, too.
[Entire table laughs for a solid minute.]
