"Somewhere on a fetid, fog-bound mud bank on [Vogsphere] there stands, surrounded by the dirty, broken and empty carapaces of the last few jeweled scuttling crabs, a small stone monument which marks the place where, it is thought, the species Vogon Vogonblurtus first arose. On the monument there is carved an arrow which points away, into the fog, under which is inscribed in plain, simple letters the words "The buck stops there.""
