Vogons are one of the most unpleasant races in the galaxy - not evil, but bad tempered, bureaucratic, officious and callous. They wouldn't even lift a finger to save their own grandmothers from the Ravenous Bugblatter Beast of Traal without orders, signed in triplicate, sent in, sent back, queried, lost, found, subjected to public enquiry, lost again, and finally buried in soft peat for three months and recycled as firelighters. On no account should you allow a Vogon to read poetry to you.
