I read this book cover to cover in one sitting. The content, is not too taxing to take onboard in one or two sittings.
Funny, yes some older known jokes are here as well as a few others perhaps forgetten but no less enjoyed on reading them here.
I would recommend it with a caveat. Be aware as to the volume of jokes presented in such books, as ebooks. i have purchased a few whereby there have nto been as many jokes as I would have liked or expected. That said do not be dissuaded in buying it for that reason alone.
