Jennings, Paula Nancy Millstone : Paula Nancy Millstone Jennings of Greenbridge, Essex, England, Earth, was (before the destruction of the Earth) known as writer of the worst poetry in the Universe. She only just barely beat out the Azgoths of Kria and the Vogons for this honor.

Jeltz, Prostetnic Vogont : Prostetnic Vogon Jeltz is the captain of a Vogon Constructor vessel, which in turn is part of the Vogon Constructor Fleet which destroyed the Earth to make way for the new hyperspace bypass. Like all Vogons, he is bad tempered, bureaucratic, officious and callous, and his favourite pastime is shouting at people. Prostetnic Vogon Jeltz also enjoys writing poetry, but this is merely to throw his mean callous heartless exterior into sharp relief. Jeltz is responsible for Ford Prefect and Arthur Dent spending 29 seconds asphyxiating in space, after a gut-mangling poetry appreciation, and an interesting conversation with the armpits of an ambitious Vogon guard.

Jatravartids : The Jatravartid People of Viltvodle Six firmly believe that the entire universe was sneezed out of the nose of a being called The Great Green Arkleseizure. They live in perpetual fear of the time they call The Coming Of The Great White Handkerchief. The Jatravartids are small blue creatures with more than fifty arms each, who are therefore unique in being the only race in history to have invented the aerosol deodorant before the wheel.

Janx Spirit : Janx Spirit is a rather potent alcoholic beverage, and is used heavily in drinking games that are played in the hyperspace ports that serve the madranite mining belts in the star system of Orion Beta. The game is not unlike the Earth game called Indian Wrestling, and is played like this: Two contestants sit at either side of a table, with a glass in front of each of them. Between them would be placed a bottle of Janx Spirit — as immortalized in that ancient Orion mining song :

“Oh don’t give me no more of that Old Janx Spirit
No, don’t you give me no more of that Old Janx Spirit
For my head will fly, my tongue will lie, my eyes will fry and I may die
Won’t you pour me one more of that sinful Old Janx Spirit”

Each of the two contestants would then concentrate their will on the bottle and attempt to tip it and pour spirit into the glass of his opponent - who would then have to drink it. The bottle would then be refilled. The game would be played again. And again. Once you started to lose you would probably keep losing, because one of the effects of Janx spirit is to depress telepsychic power. As soon as a predetermined quantity had been consumed, the final loser would have to perform a forfeit, which was usually obscenely biological.
