Ever wondered how life would be if you had a clone of yourself? Why not ask this Canadian cartoon for examples?

Carl Crashman is a lazy 14-year-old who is good at only one thing: slacking. One day, he had a rough day and he was tired of doing things he hated all the time. While blogging on the Internet, he complained about his life. Hearing his request for a clone, an online cloning company sent Carl an exact clone of himself in a box. Carl named him Carl Squared or simply C2. Even if C2 looked like him, talked like him, and walked like him, C2 was more ambitious, hard working and charming, much to Carl's advantage. Since C2 arrived, Carl has been relaxing a lot more. However, C2 really always does something opposite to what Carl wants. Carl decided to keep C2 a secret from everyone else, except his best friend, Jamie James.

The series originally lasted for three seasons (2005–07). A fourth season was added in 2010–11 for a total of 65 episodes.

* JarPotty: Used as a BrickJoke in one episode. C2 starts off in the luggage, begging for use of a washroom. Carl gives him a cup to use, since he couldn't confess to his family that he had a clone just yet. Near the end of the episode, Carl is the one who ends up in the suitcase, and drinks "some nasty soda C2 left".

Whenever Carl doesn’t fail on a test or he successfully passes an assignment, Mr. Agar always accuses Carl of cheating.
