It's by the guy who runs / draws xkcd.com web comics, and gives serious scientific answers to absurd hypothetical questions. For example: Is it possible to build a jetpack using downward firing machine guns?

Questions are weird like that, but the science is real, so an interesting read. Specially if you are a fan of xkcd.

What about all of you? What have you been reading or listening to lately?

Fun. Hilarious. The chapters are definitely longer than what I can see so far with "What If?", so that's a point to "How To?" in my book, but there are subchapters if you need them. If you enjoy science and xkcd's sense of humour it's definitely a great read.
