Clarissa Explains It All was a classic Nickelodeon sitcom that ran for 5 seasons and produced 65 episodes, beginning in 1991. Clarissa, as some preferred to call it, featured plot lines that teenagers can relate to. Clarissa's family members were her annoying little brother (Ferguson), her health nut mom (Janet), and her architect dad (Marshall). Her next door neighbor, Sam, was always welcome in her room. In fact, he used a ladder to climb through her window at any time he pleased. Clarissa also had, for a short time, a pet alligator named Elvis.

The series aired on Nickelodeon in the United States as part of their SNICK line-up from 1991-1994, lasting for 5 seasons (and continuing on in reruns for years). In 1994, the series received an Emmy nomination for 'Outstanding Children's Program'. In addition, Melissa Joan Hart, Sean O'Neal, and Jason Zimbler also received multiple Young Artist Award nominations. Melissa won 3 for her role as Clarissa.
