I got a copy of "Ba Dum Tss!" by Fred Zehl from Amazon.com.au when it was free and these are my honest thoughts. It might still be free, but I don't know at the moment. It's a collection of bad jokes, the worst jokes in the world, claims the author. Overall, there were a few good laughs. Some of them just aren't funny to me. There are others which are a bit repetitive, such as the hipster "before it was cool" type of joke that gets repeated at least four or so times. Overall, none of these jokes are particularly original; they've just been floating around on the internet for a few years and the author has compiled them in a book. The book was alright and occasionally made me laugh.
