Animaniacs is an American animated series, distributed by Warner Bros. Television and produced by Amblin Entertainment and Warner Bros. Animation. The comedy of Animaniacs was a broad mix of old-fashioned wit, slapstick, pop culture references, and cartoon violence and wackiness. The show featured a number of comedic educational segments that covered subjects such as history, mathematics, geography, astronomy, science, and social studies, often in musical form. Animaniacs itself was 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.
