Clarissa Explains It All is an American teen sitcom that aired on Nickelodeon. Created by Mitchell Kriegman, it aired for five seasons for a total of 65 episodes from March 23, 1991, to December 3, 1994, and then went into reruns.

In the series, Clarissa Darling, who is played by Melissa Joan Hart, is a teen girl who addresses the audience directly to describe the things that are happening in her life, dealing with typical pre-adolescent concerns such as school, boys, pimples, wearing her first training bra and an annoying little brother. Reruns of the show have appeared intermittently on TeenNick’s channel block The ’90s Are All That since July 25, 2011.

Britt Reid (Seth Rogen), the heir to the largest newspaper fortune in Los Angeles, is a spoiled playboy who has been, thus far, happy to lead an aimless life. After his father (Tom Wilkinson) dies, Britt meets Kato (Jay Chou), a resourceful company employee. Realizing that they have the talent and resources to make something of their lives, Britt and Kato join forces as costumed crime-fighters to bring down the city’s most-powerful criminal, Chudnofsky (Christoph Waltz).
