The Hitchhiker's Guide to the Galaxy

One of the greatest achievements in comedy. A work of staggering genius -- David Walliams
Dazzlingly inventive -- Caitlin Moran
Fizzing with ideas . . . Brilliant -- Charlie Brooker
I haven’t known many geniuses in my life. Some brilliantly smart people, but only a tiny handful would I class as geniuses. I would class Douglas, because he saw things differently, and he was capable of communicating the way he saw things, and once he explained things the way he saw them, it was almost impossible to see them the way you used to see them -- Neil Gaiman
The first book that wasn’t by Roald Dahl that really made me laugh. Arthur Dent is this humdrum person in search of a cup of tea and ends up going on mind-blowing adventures. He is so ordinary and the circumstances are so extraordinary that it was the funniest thing I’d ever read -- Robert Webb
It changed my whole life. It's literally out of this world -- Tom Baker
Really entertaining and fun -- Michael Palin
Hitchhiker’s is packed with that unique energy, all barmy and bristling and bold. This book can be witty, iconoclastic, godless, savage, sweet, surreal, but above all, it dares to be silly. Fiercely, beautifully silly -- Russell T. Davies, writer and producer of Doctor Who
He had almost a Wodehousian style and some of his phrases and jokes entered our language. He changed the way people spoke -- Stephen Fry
There has never been another writer remotely like Douglas Adams. He discovered a completely new genre – scientific wit – and having discovered it he raised it to dizzying heights -- Tony Robinson
Quite good I suppose, if you like brilliantly entertaining books written with a touch of imaginative genius -- Griff Rhys Jones
Very occasionally a book comes along that changes the way you laugh and what you laugh about -- Richard Dawkins

Sheer delight * The Times *
Magical . . . read this book * Sunday Express *
Really entertaining and fun -- John Cleese
Much funnier than anything John Cleese has written -- Terry Jones
Who is John Cleese? -- Eric Idle
I know for a fact that John Cleese hasn’t read it -- Graham Chapman
