I don't often find fiction funny, but every once in awhile something tickles my fancy.  I got a chuckle at Lorna Landvik's Angry Housewives Eating Bon Bons and Welcome to the Great Mysterious.  Also, Brendan O'Carroll's Agnes Browne and the Chisellers gave me a good laugh even with the serious plot lines.  The Bed and Breakfast Mysteries by Mary Daheim are humorous too.

Edited to add:  The Ladies #1 Detective Agency books are also worth a laugh.

What novels have made you laugh?

This is a good topic, Christopher Moore comes to mind.  My hubby reads all his. The Bachelor Brother's Bed and Breakfast, an old one but a good one.  Garrison Keillor, Lake Wobegon,  some of Tom Bodett, also older books.  I have a book in mind but I just can't recall the title.

I enjoy Bill Bryson, he's humous but that's non-fiction.  For kids I enjoyed Seinfeld's book about Halloween.

Happy reading

Few writers get humor right.  In contemporary fiction, I'd say George Saunders is consistently one of the funniest guys out there.  Try out Civilwarland in Bad Decline (short stories) or Pastoralia (short stories), which is his early work.

The funniest book from start to finish I've ever read is The Floating Opera by John Barth.  I laughed so hard that I cried!  But Barth's humor isn't for everyone.  I lent the book to my girlfriend and she hated it.  To each his own, I guess.

I laugh out loud at Janet Evanovich's Stephanie Plum series.  Love the Grandma Mazur character!!

I like Bill Fitzhugh's books. Pest Control is one of his best.

Just finished "Monkey Love" by Brenda Scott Royce and it is hilarious fun.

The Miss Julia books by Ann somebody, and the Thursday Next books by Jasper Fforde are both laugh out loud funny.

 Janet Evanovich's entire "Stephanie Plum" series is hilarious! It will literally have you laughing out loud. I started with *One For The Money* and have read every single one.

 When both the owner of our 30 some year old book trading store and the head librarian recomended this series I was to say the least ...doubtful...I mean the names of the books threw me off completely.

I found out later that the name has nothing to do with the book; ok that sounds strange but the readers actually name the books . They just submit names that will sound suitable with the next number in the series.

Give them a try, you might be pleasantly surprised like me.

HAPPY READING.

Try books by Christopher Moore (especially "Lamb"),  Carl Haiissen, or Tom Dorsey.

Their sense of humor is often wierd.  You need to read Haiissen and Dorsey in order of publication since references/story lines are often tied to earlier books/characters

GOOD LUCK

 Anything by PG Wodehouse will give me a giggle, and right now I am reading "A Dog's Life" by Peter Mayle and I can't stop laughing! If you're a dog lover, give this one a try!

Janet Evanovich's Stephanie Plum series is hilarious!

"Agnes And The Hitman"  and  "Faking It"..........both by Jennifer Crusie.  They had me laughing out loud.

I've found Christopher Moore's books kind of hit or miss. I really really like some of them (the books set in Pine Cove are great, and I really enjoyed The Stupidest Angel too) but found some of them to have sort of 'forced' humor which makes them have the opposite effect on me. (His latest, Fool, was very mediocre, I thought.)

If you like word play, puns, and wacky British humor, I'd suggest a couple--Jasper Fforde and Robert Rankin.

I have to agree about Evanovich's Stephanie Plum books.  Parts of those books are the closest thing to slap-stick you can get in print .

You're Ugly Too by Loorie Moore is really funny!

Terry Pratchett and Robert Rankin.

Piers Anthony to a lesser extent.

I second Bill Bryson and Terry Pratchett. I also like some of Kurt Vonnegut's stuff. I don't care for Christopher Moore.

Anything by P.G. Wodehouse or by Jean Shepard

I just finished Jane Austen in Boca and it was laugh out loud funny. 

Fast Women by Jennifer Cruise is also very funny.  As is Welcome to Temptation.

One of my all-time favorite books is A Prayer for Owen Meany. It's hilarious, serious, and sad all at the same time.

I just finished a young adult novel, The Extraordinary Adventures of Alfred Kropp, and it was HILARIOUS.

My vote is for Bill Bryson (non-fiction)  and Christopher Moore (funny, but dark)

I love Marian Keyes, the books about the Walsh Sisters:  Water Melon, Rachel's Holiay, Angels, Is Anybody Out There

Marian Keyes is funny, but yet serious and full of wicked British Humor.

bill bryson cracks me up.

i read last year the book "the screwed up life of charlie the second" by drew ferguson ... hilarious! it's currently wishlisted, but i have it as a unpostable if anyone is interested in it. you gotta be pretty opened minded as it's about a gay son, but it's super funny.

Tietam Brown by (yes the wrestler) Mick Foley

Later, at the Bar: A Novel in Stories by Rebecca Barry

Gold by Dan Rhodes

The Wonder Spot by Melissa Bank
very funny book.

Dark At the Roots by Sarah Thyre
not fiction but funny
