The Hitchhiker’s Guide to the Galaxy is a wholly remarkable book. More popular, certainly more successful than the Celestial Home Care Omnibus, better selling than Fifty-Three More Things to do in Zero Gravity, and more controversial than Oolon Colluphid’s trilogy of philosophical blockbusters Where God Went Wrong, Some More of God’s Greatest Mistakes and Who is this God Person Anyway? 

Arthur: Ford.
Ford Prefect: Yes?
Arthur: I think I’m a sofa.
Ford Prefect: I know how you feel.

Arthur: Where is he?

Vogon poetry is widely accepted as the third worst in the universe.

Arthur: I think I’m gonna be sick!
Zaphod: Hey, do it in the trash can, Earth man, this ship is brand new.
