The 27 Club

Zaphod Beeblebrox () is a fictional character in the various versions of the comic science fiction series The Hitchhiker's Guide to the Galaxy by Douglas Adams.

He is from a planet in the vicinity of Betelgeuse, and is a "semi-half-cousin" of Ford Prefect, with whom he "shares three of the same mothers". Because of "an accident with a contraceptive and a time machine", his father, grandfather, and great-grandfather are actually his direct descendants.
