The Grim Adventures of Billy and Mandy Season 4 Episode 3

The Bad News Ghouls / The House Of No Tomorrow

"The Bad News Ghouls" After Billy's baseball team loses badly against Mindy's, Grim decides to coach them. Mandy is not allowed on the team, as Billy is reluctant to let girls play, although he does not realize Mindy is a girl too. Mandy puts on a baseball cap and, assuming the role of "Manfred", pitches for Billy's team anyway. With additional help from ghoulish players which played in the Underworld Little Leagues alongside Grim, Billy's team wins when Pud'n hits a home run. "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.
