Because everything in Hollywood must be revived these days, the Animaniacs are back after being locked in that Warner studio water tower for more than 20 years. Led by the fictional siblings Yakko, Wakko and Dot, the super-meta cartoon featured slapstick humor and cultural references that appealed to both kids and adults alike. Hulu has released a new batch of Animaniacs episodes and much of the original voice cast returns — though this time around you should expect fewer Goodfellas jokes and more cracks about presidential elections.
