Brainstem (found preview version of "Pinky and the Brain" song; 1995)
Pinky and the Brain is a spin-off from the animated series Animaniacs that premiered in 1995 about two mice who develop different schemes to take over the world.
The third episode of the show ends with a song called "Brainstem" about the different parts of the brain. A month before the show's premiere, several WB affiliates, including KWBP 32 in Portland, Oregon (now known as KRCW-TV) showed a different version of the song where Brain says "Now, let's get this show on the road. Yes!" instead of "That oughta keep the little squirts happy. Yes!" at the end,[1] in a similar manner to how the song "Yakko's World" from Animaniacs was previewed before it aired with different narration at the beginning before its' premiere. Aside from a brief mention on a tribute page to Kids' WB, no footage of this version has surfaced.
