Animaniacs

Animaniacs is an American animated comedy television series created by Tom Ruegger. It is the second animated series produced by Amblin Entertainment in association with Warner Bros. Animation during the animation renaissance of the late 1980s and early 1990s. Animaniacs first aired on Fox Kids from 1993 to 1995 and new episodes later appeared on The WB from 1995 to 1998 as part of its Kids' WB afternoon programming block. The series had a total of 99 episodes and one film, Wakko's Wish.

Animaniacs is a variety show, with short skits featuring a large cast of characters. While the show had no set format, the majority of episodes were composed of three short mini-episodes, each starring a different set of characters, and bridging segments. Hallmarks of the series included its music, character catchphrases, and humor directed at an adult audience.
