Thing number one, which is important: I am not making this book up.
See, there’s this self-help book, in which the Japanese author recommends exercise, positive thinking, getting in touch with your body’s energy, diet changes and fasting to cure depression, cancer, family and personal problems of all stripes, to achieve success in life, to look and feel younger, and to be able to instantly apprehend all that can be known about objects and people using the power of your brain. Which, okay, is not that different from many other self-help books and/or new age treatises. The difference between those books and this one is they they were not written in Japanese and then seemingly passed through Babelfish a couple of times. Nor do the first quarter of these other books consist of a mishmash of disordered Usenet postings from the turn of the millennium, before it sank beneath the waves of the internet never to be seen again.
Most importantly though, these other books do not recommend that you “constrict anus 100 times every day and then dent navel 100 times every day after constricting anus 100 times every day, following the lifestyle of long-lived British.” They do not explain that after fasting for three weeks, you will rid yourself of “a big bucketful of old, black excrement” which will weigh 4-5 kilograms. They do not exhort you to concentrate your third attention and send out your immaterial fiber at objects patiently for an hour a day for 3-5 years or possibly 10. They do not spontaneously speculate about the ways in which Al Gore and George W. Bush probably follow most of this advice and are able to * * twice or three times in succession without pulling out, as a result. (Okay, I may have taken ordering liberties with that last part; but it’s not an unfair assessment.)
Here’s my point. I don’t know if constricting anus 100 times every day is an effective way to good-bye depression or not. But reading this book? It really seems to do the trick. Sure, there’s a slow part in the middle, but mostly, more laugh density than most intentionally comedic books I read. Also, assuming you hadn’t heard of this book before, be honest with yourself. You’ve constricted your anus at least once while reading this, haven’t you? (Be honest with yourself. Not with me. I don’t want to know details, here. Come on, people! Keep me out of your anus!)
 Historical note from 2020: Babelfish no longer exists. I’d recommend translate.google.com as a good alternative.
