Q. What's the difference between a used-car dealer and a computer salesman?

A. The used-car dealer knows he's lying. [Some versions add: ...and probably knows how to drive.]

This reflects the widespread hacker belief that salescritters are self-selected for stupidity (after all, if they had brains and the inclination to use them, they'd be in programming). The terms `salesthing' and `salesdroid' are also common. Compare marketroid, suit, droid.
