which is the funniest book you ever read?

Any book by Pierre Desproges.

Terry Pratchett's Discworld series,

and Douglas Adams' Hitchiker's guide to the Galaxy,

Evelyn Waughn' Scoop.

I just can't decide which is best.

King Fortis the Brave - it's a fantasy adventure book, but the Ward is one of the funniest characters I've ever read!

The Electric Acid Koolaid Test by Ken Kesey. Anything by Rear Admiral (Ret.) Daniel Gallery. Any of the MASH books.

The Non-Existence Knight. It's similar humor to Monty Python.

I've also read exerts from A Confederacy of dunces and me talk pretty one day that were very funny.

Also anything by Dave Barry or either of Bruce Campbell's two books are very funny.

David Sedaris' Me Talk Pretty One Day. Hysterical short story collection. Other entertaining titles include Hugh Laurie's The Gun Seller, Dodie Smith's I Capture the Castle (though the other events lead for an overall bittersweet tone), and Christopher Moore's Lamb (though it is possible that it may offend some).

Catch 22 by Joseph Heller and A Confederacy of Dunces by Toole

Maxwell Smart and The Ghastly Ghost Affair

Any book in the Stephanie Plum series works of Janet Evanovich

Angry Housewives Eating Bon Bons

-or-

Any Ann George Book.

The Hitchhikers Guide to the Galaxy, by Douglas Adams.
