"We should do something," I said. "Can the something be play blind-guy video games while sitting on the couch?" "Yeah, that's just the kind of something I had in mind." So we sat there for a couple hours talking to the screen together, navigating this invisible labyrinthine cave without a single lumen of light. The most entertaining part of the game by was far trying to get the computer to engage with us in humorous conversation: Me: "Touch the cave wall." Computer: "You touch the cave wall. It is moist." Isaac: "Lick the cave wall." Computer: "I do not understand. Repeat?" Me: "Hump the cave wall." Computer: "You attempt to jump. You hit your head." Isaac: "Not jump. HUMP." Computer: "I don't understand." Isaac: "Dude, I've been alone in the dark in this cave for weeks and I need some relief. HUMP THE CAVE WALL." Computer: "You attempt to ju--" Me: "Thrust pelvis against cave wall." Computer: "I do not--" Isaac: "Make sweet love to the cave." Computer: "I do not--" Me: "FINE. Follow left branch." Computer: "You follow the left branch. The passage narrows." Me: "Crawl." Computer: "You crawl for one hundred yards. The passage narrows." Me: "Snake crawl." Computer: "You snake crawl for thirty yards. A trickle of water runs down your body. You reach a mound of small rocks blocking the passageway." Me: "Can I hump the cave now?" Computer: "You cannot jump without standing." Isaac: "I dislike living in a world without Augustus Waters." Computer: "I don't understand--" Isaac: "Me neither. Pause."
