In an interesting twist, a new book trailer from The Onion spends more time telling you how to read a book than it does showing you the book.

All the parents in the GalleyCat audience can relate to The Book Bjorn, a fake infomercial for a sling to help you carry an oversized copy of The Onion Book Of Known Knowledge.

Check it out: “Replete with an astonishing assemblage of facts, illustrations, maps, charts, threats, blood and additional fees to edify even the most simple-minded book-buyer, The Onion Book Of Known Knowledge is packed with valuable information–such as the life stages of an Aunt; places to kill one’s self in Utica, New York; and the dimensions of a female bucket, or ‘pail.’ With more than 1,500 entries spanning all 27 letters of the alphabet, The Onion Book Of Known Knowledge must be purchased immediately to avoid the sting of eternal ignorance.” (Via Little, Brown and Co.)
