Ford Perfect

Ford Prefect (a.k.a. Ix) was a friend of Arthur Dent, and the semi-cousin of The President of the Galaxy, Zaphod Beeblebrox. While on Earth, he posed as an out-of-work actor until the Vogons arrived, when he revealed to Arthur that he was not in fact from Guildford, but from a small planet somewhere in the vicinity of Betelgeuse, and that he was not an out-of-work actor, but a researcher for The Hitchhiker’s Guide to the Galaxy.
