I can't cite specific books, but in general, any of them wherein the author has all the facts wrong on a subject that I know very well. (I've seen this in both fiction and non-fiction.). For instance, years ago, I read one that had a subplot about a US Marine. Having served in the Marine Corps myself, I could spot a novice from fifty feet away. The author must have only seen movies about the military as opposed to being a veteran or as opposed to researching the subject, because the far-fetched scenarios and cliche-ridden references were as silly as could be. I was laughing at how ridiculous everything was laid out, and the storyline was not comedic at all. ~
Sometimes you have to distort the truth slightly to move the story along - Heinlein used to do that routinely. He knew the straight of it, being ex-Navy, but had to curb what he knew to prevent it from getting in the way of a good yarn. Of course, there's no excuse in non-fiction.
I don't think that's what happened with the book I referenced. This was more of someone trying to seem as if he/she knew the subject matter when that was not the case. ~
No doubt about it for me, Shirley Jackson's two memoirs about her and her husband raising their young children. Even the titles are hilarious!
"Life Among the Savages" and "Raising Demons"
I laughed and laughed! So funny!
Though I'm biased (Jackson is one of my very favorite authors), I did not expect to laugh so much. I had read much of her other works before I read these two books. Her non-fiction can be incredibly different than her often-strange/creepy fiction. :)
For starters, the Bible and the Quran are so ridiculous that they make me laugh. Any book that has gross errors gives a laugh. Some 007 novels have James Bond carrying his Walther PPK pistol in a "Burns-Martin" holster. Actually, the Berns (not Burns)-Martin holster mentioned was for pocket revolvers, rather than semi-automatics. Also, 007 had his Walther PPK in his shoulder holster and had a Smith & Wesson Centennial revolver in his car. Both handguns are pocket size, and the S&W fits in his Berns-Martin holster. In a Carter Brown suspense novel, someone used a ".38 Magnum". I think he meant .357 Magnum. Years after Ian Fleming died, John Gardner wrote a series of 007 novels. 007 switches guns. In one novel, he carries a 1903 Browning pistol that uses an obsolete 9mm Browning cartridge. Using an antique pistol that has no available replacement parts and fires cartridges that he cannot buy is a very bad idea.
