Could you share the funniest books that you have ever read?

I am looking to laugh. To guffaw. To snort with laughter and spill popcorn while I read.

To do that, I'd like to ask your help. I'd very much appreciate the titles of the funniest books you've ever read. I read at an adult level (though I'm really quite immature!) and I'm no wilting violet when it comes to humor.

Please, bring it on! Thanks so much.
