Pinky and the Brain first appeared as a recurring segment on Animaniacs in 1993 before getting their own Warner Bros animated series in 1995. The two laboratory mice, the tall dim-witted Pinky and the serious megalomaniac Brain, opened many stories with the same nightly exchange about their plans. That repeated routine turned the question into one of the show's most quoted signatures. Clips of it still circulate in nostalgia posts and short edits because the setup is instantly recognised by viewers who grew up with 1990s cartoons.
