Clarissa Explains It All is an American situation comedy television series from Nickelodeon starring Melissa Joan Hart. It was created by Mitchell Kriegman, encompassing 65 episodes shown during five seasons. As events unfold in her life, Clarissa explains to the viewer the motivations behind people's actions. The main characters in the show are Clarissa Darling, her family (consisting of her father Marshall, her mother Janet and her little brother Ferguson) and her best friend Sam living in a small suburban town in Ohio. Clarissa and Sam's relationship was a novelty on television at the time, due to few television series allowing a girl and a boy to be merely friends without romance blossoming. (One episode featured the idea of their having a romance, but ultimately ended without their getting together.) Clarissa also had a pet baby caiman named Elvis which she kept in a kiddie-sandbox in the left corner of her room. Elvis lasted only the first few episodes of the first season.
