Share a book that made you laugh.
This question is a re-do of one from a couple of years ago, but I know a lot of you weren't in the neighborhood back then, so I'll re-do my answer (also, because I don't read a lot of "funny" books, this one is still pretty high on the list…).
If you want a laugh read: The Sex Lives of Cannibals: Adrift in the Equatorial Pacific by J Maarten Troost.
The protagonist — if this book can be said to have one — is a disenchanted, serial academic type in his late 20s that doesn't seem to need or want to work for a living. As an adventure, he heads off to the south seas with his wife who has taken a job doing third-world aid. His ideas of an idyllic paradise complete with swaying palm trees and nymphesque micronesian women is quickly disabused. What follows is one of the funniest travelogues I've ever read — his sheer incredulity that this world EXISTS in the same one with cell phones, cable tv, and modern transportation is hysterical.
