This is an excellent and well-written book. However, it has to be the worst case of proofreading failure that I have seen. It clearly was scanned and never even superficially inspected. Random punctuation appears in the middle of sentences; words are exchanged for other words: "be" becomes "he" at least 8 times; "the" is 12 times written as "die." It is so bad that it is difficult to tell whether something is a joke or is the actual text. For example, on the very first page: "there are some farts that I hardly know and other farts that I don't know at all!"
