This dynamic pair began a journey through space aided by a galaxyful of fellow travelers: Zaphod Beeblebrox—the two-headed, three-armed ex-hippie and totally out-to-lunch president of the galaxy; Trillian, Zaphod’s girlfriend, whom Arthur tried to pick up at a cocktail party once upon a time zone; Marvin, a paranoid, brilliant, and chronically depressed robot; and Veet Voojagig, a former graduate student obsessed with the disappearance of all the ballpoint pens he’s bought over the years.
