Carl Crashman is a lazy 14-year-old who is only good at one thing: slacking. After a rough day and being tired of constantly doing things he hated, he was blogging on the Internet and complaining about his life when he accidentally ordered a clone from a spam e-mail using his fingerprint, a yearbook photo and a scabby band-aid; Carl is shocked when an online cloning company sends him an exact clone of himself in a box. Carl names him C2. Even though C2 looks like Carl, talks like him (albeit with a higher-pitched voice), and walks like him, C2 is more ambitious, hard-working, and charming, much to Carl's advantage. Since C2 arrived, Carl has been slacking off a lot more. However, C2 often does the opposite to what Carl wants. Carl decides to keep C2 a secret from everyone else except his best friend Jamie James.
