Back when Animaniacs and the Pinky and the Brain spin-off were first airing there was a fan theory going around that Pinky was actually the super genius mouse and Brain was the moron. I remember feeling that this theory had a lot of merit at the time, but it’s been so long since I’ve seen the show I don’t know if I can confidently say to what extent it holds up. If I ever get around to rewatching it, I’m definitely going to be watching through that lense though.
