They generally become bureaucrats in the galactic government. Their unpleasant demeanour makes them ideally suited to such employment. Vogons have dark green rubbery skin, waterproof enough to survive indefinitely at sea depths of down to a thousand feet with no ill effects. They have highly domed noses above small piggy foreheads. One such Vogon is Prostetnic Vogon Jeltz, of the Vogon Constructor fleet. Having destroyed the Earth in order to make way for a hyperspace bypass, he then proceded to read some of his poetry to two helpless victims. They write some of the worst poetry in the known universe.

An example:

O freddled gruntbuggly…
…thy micturations are to me
As plurdled gabbleblotchits on a lurgid bee.
Groop I implore thee,
my foonting turlingdromes.
And hooptiously drangle me with crinkly bindlewurdles,
Or I will rend thee in the gobberwards with my blurglecruncheon,
see if I don’t!
