Mistakes Were Made


Stephan Pastis - 2013
    Created by New York Times best-selling cartoonist Stephan Pastis.Take eleven-year-old Timmy Failure — the clueless, comically self-confident CEO of the best detective agency in town, perhaps even the nation. Add his impressively lazy business partner, a very large polar bear named Total. Throw in the Failuremobile — Timmy’s mom’s Segway — and what you have is Total Failure, Inc., a global enterprise destined to make Timmy so rich his mother won’t have to stress out about the bills anymore. Of course, Timmy’s plan does not include the four-foot-tall female whose name shall not be uttered. And it doesn’t include Rollo Tookus, who is so obsessed with getting into "Stanfurd" that he can’t carry out a no-brainer spy mission. From the offbeat creator of Pearls Before Swine comes an endearingly bumbling hero in a caper whose peerless hilarity is accompanied by a whodunit twist. With perfectly paced visual humor, Stephan Pastis gets you snorting with laughter, then slyly carries the joke a beat further — or sweetens it with an unexpected poignant moment — making this a comics-inspired story (the first in a new series) that truly stands apart from the pack.
