The Jetsons season 2 episode 9
Episode title: S.M.A.S.H.
Jane accidentally crashes Mr. Spacely's car that she borrowed, which causes him to merrily blame George, making him a virtual slave and groveler, until it was discovered that the brakes are jammed by a piece of fine space china from one of Spacely's space china collections. This absolves the Jetsons, and then the tables are turned and a furious and humiliated Spacely becomes the reluctant servant of George.
