Pinky and the Brain is an American animated television series.
It is a spin-off television from Animaniacs, with 65 episodes produced by Steven Spielberg and Warner Bros. Animation. Later, they appeared in the unsuccessful series, Steven Spielberg Presents Pinky, Elmyra & the Brain.
Pinky and Brain are genetically enhanced laboratory mice who reside in a cage in the Acme Labs research facility. Brain is self-centered and scheming; Pinky is good-natured but feebleminded. In each episode, Brain devises a new plan to take over the world, which ultimately ends in failure, usually due to Pinky's idiocy or the impossibility of Brain's plan. In common with many other Animaniacs shorts, many episodes are in some way a parody of something else, usually a film or novel. The opening song is preceded by the following dialogue:
Pinky: "Gee, Brain, what do you want to do tonight?"
The Brain: "The same thing we do every night, Pinky—try to take over the world!"
