A ridiculous and obviously prevaricating excuse for failing to meet an obligation. It dates from the late 1900s and is so well known that a Boston Globe headline for a book review of The Shallows: What the Internet Is Doing to Our Brains by Nicholas Carr played on it, “The Internet Ate My Brain” (June 6, 2010). A Washington Examiner column by Timothy P. Carney about a bill provision allowing the U.S. Patent and Trademark Office to accept late applications for patent extensions called it “The Dog Ate My Homework Act” (March 20, 2010).
