The Hitchhiker's Guide to the Galaxy, sometimes abbreviated H2G2, is a science-fiction comedy series originally produced as a radio series, created by Douglas Adams. The name may be used to refer to the radio episodes, the series of five books, the stage shows, the BBC television series, a computer game, the 2005 movie, or the Guide of the story, though most commonly the books.
There are a number of variations and contradictions between versions of The Hitchhiker's Guide, but the basic storyline remains the same. This follows an Englishman named Arthur Dent who accompanies Ford Prefect, an alien from a small planet in the vicinity of Betelgeuse and reporter for the Guide, in escaping the destruction of Earth by the Vogons. They are later rescued by the automatic systems of the Heart of Gold, a ship powered by the Infinite Improbability Drive and crewed by Zaphod Beeblebrox, Ford's half-cousin; Trillian, a mathematician, astrophysicist, and very nice girl Arthur met at a party in London; and Marvin the Paranoid Android, depressed robot. They then go looking for the legendary planet of Magrathea, which made planets when the galaxy's economy could afford it.
H2G2 and the PPC
Being to science fiction what Discworld is to fantasy—a snarky but loving satire of the genre—H2G2 enjoys a good deal of popularity among PPCers. Many show their appreciation by celebrating Towel Day on May 25.
Agents Rez and Flip are known to have brewed a dangerously potent Bleeprin derivative from H2G2's Pan Galactic Gargle Blaster, an alcoholic beverage invented by Zaphod Beeblebrox. "The best drink in existence," according to The Hitchhiker's Guide to the Galaxy, the effect of drinking a Pan Galactic Gargle Blaster is "like having your brains smashed out by a slice of lemon wrapped round a large gold brick." The Pan Galactic Gargle Bleeprin Blaster can cause permanent amnesia if imbibed in excess.
Agent Rez may be from this continuum, since she was born on a small planet near Polaris and spent some time with a space pirate crew before joining the PPC, but this is unconfirmed.
The unfortunate pot of petunias from H2G2, although sentient, bears no relation to the Flowers (as far as anyone knows).
