u"Here is what to do if you want to get a lift from a Vogon: forget it. They are one of the most unpleasant races in the Galaxy. Not actually 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 \u2013 signed in triplicate, sent in, sent back, queried, lost, found, subjected to public inquiry, lost again, and finally buried in soft peat for three months and recycled as firelighters. The best way to get a drink out of a Vogon is to stick your finger down his throat, and the best way to irritate him is to feed his grandmother to the Ravenous Bugblatter Beast of Traal. On no account should you allow a Vogon to read poetry at you.
