The Hitchhikers Guide To The Galaxy describes the Pan Galactic
Gargle Blaster as a potent drink invented by Zaphod Beeblebrox. The
effects have been likened to having your brains smashed out with a
slice of lemon wrapped round a large gold brick.
There are many voluntary organizations which will help to
rehabilitate you after you've had one.
The Guide has instructions for mixing a Pan Galactic Gargle
Blaster yourself:
1. Take the juice from one bottle of that Ol' Janx Spirit.
2. Pour into it one measure of water from the seas of
Santraginus V.
3. Allow three cubes of Arcturan Mega-gin to melt into the
mixture (it must be properly iced or the benzine is lost).
4. Allow four litres of Fallian marsh gas to bubble through it,
in memory of all those happy Hikers who have died of pleasure in
the Marshes of Fallia.
5. Over the back of a silver spoon float a measure of Qualactin
Hypermint extract, redolent of all the heady odours of the dark
Qualactin Zones, subtle sweet and mystic.
6. Drop in the tooth of an Algolian Suntiger. Watch it dissolve,
spreading the fires of the Algolian Suns deep into the heart of the
drink.
7. Sprinkle Zamphuor.
8. Add an olive.
9. Drink ... but ... very carefully ...
