'Dial C For Chaos' by Bob Block

When Robert tries out his four new Entertainer Robots, Eric immediately complains: he has recently been reading Karl Marx, and vehemently objects at the ‘exploitation’ of his fellow androids. Concerned with his robots’ ability to sing, Robert uses Eric to test out a new program; the long-suffering robot is soon belting out show tunes at the top of his voice – not only does his singing shatter glass, but it also smashes the binocular lenses of Gimble and Marken, who are spying from a nearby house. Katie runs off with the Entertainer Robots’ remote control, thinking it pretty; Robert chases after the dim-witted android, but Angela overhears him, and immediately suspects her fiancé of having a secret girlfriend...
