Inasmuch as the animated series Pinky and the Brain was poised to undergo a title and format change in September of 1998, ultimately re-emerging as Pinky, Elmyra and the Brain, a scant seven episodes were filmed for the series' abbreviated fourth season. And three of those episodes were comprised of a single plotline, in which genetically engineered lab mice (and would-be world conquerors) Pinky and The Brain are brainwashed (actually all they need is a light rinse) by Brain's arch-rival Snowball, whereupon they blindly endeavor to "stupidize" the world's population by performing the dreaded "Scheerskahoven." Later on, the boys stage a "reunion special" for the express purpose of hypnotizing mankind with a lethal dose of banality. And, in the series' typical topsy-turvy fashion, the series finale is actually the obligatory "origins" episode, in which we learn for the first time how Pinky and the Brain came to call the ACME Laboratories their home.
