Hank Zipzer the world's greatest underachiever:

According to ten-year-old Hank Zipzer, there are many reasons why he shouldn't have to do homework, e.g. every pen he owns has run out of ink, his thoughts are controlled by alien beings, he's allergic to lined paper... Or could it just be that Hank has dyslexia and doesn't want to look stupid? In this bind-up of the first two highly popular books in the series, Hank's ingenious plans to avoid doing his homework end in comic disaster as he accidentally floods his classroom and causes mayhem in his mum's deli, The Crunchy Pickle ... by trying to hide his school report in the meat grinder!
