The best thing about Animaniacs and their spinoff, Pinky and the Brain, was their total devotion to making Warner Brothers cartoons like they did in the “old days”… in other words, with high quality animation, real music, and hilarious gags.
Another element of the old WB toons that they borrowed was their level of sophistication. They played to the adults with political humor, double entendre, and pop culture references that the kids wouldn’t get.
Sometimes, even the adults didn’t get it.
For example, I never realized that the episode entitled Yes, Always, in which we see the Brain doing some voiceover work, is practically a word-for-word recreation of an outtake of Orson Welles recording a frozen peas commercial and getting pissed off at the hapless director.
Now, someone has taken the original recording and made The Brain overdubbed with Orson Welles.
