Calvin and Hobbes by Bill Watterson for August 31, 1989
Clavin: Ok, the rist thing our robot needs is a head. Hobbes: Should we use a coffee can? Calvin: No, that's too small. The head has to hold this tape recorder. See, I'be made recordings for the robot's voice! Hobbes: Really? Calvin: Sure! This way, our robot not oly communicates, but we can also "program" him to have the proper personality! Hobbes: Personality? Calvin: Right. Robots should be respectful. Tape recording: *click* How may I ease your life, oh grand exalted master?
