The Electric House (1922)

A rich man is so rich that he hires experts with high salary to transform his villa into a fully automated modern house. A young man with a doctorate in botany (Buster Keaton Buster Keaton) applied for the job, but confused his degree with the two people sitting next to him and became a doctor majoring in electricity. The young man was willing to go back on his promise, but for the sake of the rich daughter's beauty and closeness, he accepted it. Soon after, the rich man and his family went on holiday by car, leaving a young man to renovate the house. He crammed his feet and began to work aggressively with a textbook on the basics of electricity. Time is fleeting, a few days later the rich return, waiting for them is an unimaginable and amazing fully automated modern house.
