There was a recent car commercial, where they rapidly flashed scenes of the process of car design, with a voice-over reading "Bring out the designers. Bring out the mechanics. Bring out the nerds." Each sentence would show a stereotypical example of each. The designers were in a bright Apple-store-like office, wearing fashionable glasses. The mechanic was a long-haired guy holding a wrench.

And the nerds were astronauts, in launch suits, presumably walking towards a space launch.
