This is a collection of web comics which became fairly well-known. Each strip is standalone with topics ranging from relationships to politics to astronomy. Not all of the comics are of the same quality, some of them are funny, and some just raise interesting questions, while others somewhat incomprehensible. The most famous one gave the title of the book and is - for some reason - not included in it (it is on the cover, but without the caption).
I do not regret purchasing of the book and reading it, but I am not sure whether I ever reread it again: 3 stars.
