If you're seeking citizenship in the U.S., you might not want to study for the exam using the 101st edition of "Twenty-Five Lessons in Citizenship." Because it's riddled with factual errors.

The best-selling study guide, published by D.L. Hennessey (f'real), has got all the information a person technically needs to take the citizenship exam in California, and includes some "bonus facts," like "Alexander Hamilton was a president" (which anybody who watched that old Got milk? commercial, could tell you isn't true). The reporter who discovered the errors contacted the publisher, who was (unsurprisingly) mystified. Other mistakes include the assertion that the "Superior Court" is the highest court in California and that participating in elections is mandatory.

We're secretly wondering if "D.L. Hennessey" isn't the vaguely rap-inflected nom de plume of one Lou Dobbs.
