The Grim Adventures Of Billy and Mandy Season 3 Episode 17 - The Bad News Ghouls / The House of No Tomorrow >While at Sassy Cat Land, the theme park dedicated to Sassy Cat (and to ridiculously long lines), Billy, Mandy, and Grim stumble upon a closed attraction, a futuristic "house of tomorrow". Inside, they find Master-Control, a sentient and autonomous, thinking, feeling artificial intelligence computer program claiming to know everything (and wishing death upon the trio when Billy angers him), and Tom Smith, a tour guide that became trapped in the house when it closed forty years ago. Tom explains that the attraction closed when a kid, actually Billy's dad, annoyed Master-Control with his dumb questions and the robots started attacking the humans. Billy, Mandy, and Grim exit the house unharmed, but Tom misses his opportunity to escape and is left behind again.
