“One cannot understand an economy without researching the activities of all its participants, and the process through which they are born, taught, and defended by their families. To try to do so is, quite simply, stupid. That Nobel laureates and entire economic departments pretend to, and that policies in great countries is sometimes made on such pretenses makes it no less stupid.

“One of the major difficulties Trillian experienced in her relationship with Zaphod was learning to distinguish between him pretending to be stupid just to get people off their guard, pretending to be stupid because he couldn't be bothered to think and wanted someone else to do it for him, pretending to be outrageously stupid to hide the fact that he actually didn’t understand what was going on, and really being genuinely stupid. He was renowned for being amazingly clever and quite clearly was so—but not all the time, which obviously worried him, hence, the act. He preferred people to be puzzled rather than contemptuous.”

“I choose a lazy person to do a hard job. Because a lazy person will find an easy way to do it.”
