Wallace and Gromit's World of Invention Episode 3 - Home Sweet Home Episode Title:Home Sweet Home.Episode Description:Wallace and Gromit look at ingenious inventions for the home. From 1940s household robots and strange humanoid butlers to cutting-edge labour saving devices, we travel around the world to explore the social history of domestic life through inventions. We visit the home of iconic inventor Trevor Baylis - the man who revolutionised the radio - and visit 'George', one of the first walking humanoid robots ever built, as he is brought to life for the first time in sixty years by his creator, Tony Sale. During this episode Wallace had invented a L.A.D. (Labour Assisting Device) bot (which bears some resemblance to the Cooker from A Grand Day Out) replacing Gromit, who becomes jealous of it. At the end, when Wallace (inspired by footage of the Beer Launching Fridge) reprograms the L.A.D. to throw tea to him, Gromit pours some himself inside the bot when Wallace was not looking. Then the L.A.D. was out of control and starts to throw things at Wallace and Gromit refuses to help. No "Curiosity Corner" segment here, though Gromit was seen relaxing in it at the end of the episode.
