. . "American History! is an American history textbook developed by the Primary Middle School Institute for Nonprofit Grading, or PMSING, for use by 8th grade students in American History classes. Using the innovative Sit down, Shut up, and Read method, our goal is to alleviate teachers of the heavy and tedious burden of teaching by eliminating comprehension, comprehensibility and education for the sake of memorization and stifling imagination. Due to the inherent laziness of educators, the textbook is not expected to cover all of America's history by the deadline."@en . "July 2007"@en . . "UnBooks:American History!"@en . . "2156983"^^ .
