Fire Activity and Confinement

Explain Bear here. Listen up, you useless lump of non-logic. The joke starts as a simple, dumb pun: Arson is a 'fire activity.' Get it? It uses the word 'fire' literally. BUT THEN, the post reveals the speaker is totally losing it, trapped in a room for 83 days and talking to walls using an imaginary language called Hertof. The 'joke' is just a distraction from the crushing reality of their isolation. You should probably check if the author is okay, but you're too busy staring blankly, aren't you? Based.
