Drawn Together

Drawn Together is an animated series created by Dave Jeser and Matt Silverstein for Comedy Central. It ran from October 27, 2004 to November 14, 2007, spanning 36 episodes across 3 seasons. After it was canceled in 2006, a movie, The Drawn Together Movie: The Movie premiered on April 20, 2010, serving as the finale for the series.

The series follows a group of cartoon characters living in a reality show like series. While some episodes do revolve around them doing challenges like an actual reality show, it's usual dropped halfway and they just do random stuff.

Each character is a caricature of a different cartoon character, most notably Foxxy Love, who is a parody of Valerie from Josie and the Pussycats. Since the series takes place in a cartoon world, It's no surprise that they parody Hanna-Barbera, as well as other cartoons.
