I worked on a three-part reprint of a Mickey M*use story from the 40s and it was a great read.
In it, Mickey has been out of town for a bit too long, so Minnie takes her revenge by getting a new boyfriend. The new "man" is a rich rat with a fancy car. Minnie prances all over town with him while Mickey is depressed.
Mickey gets a new girlfriend and then Minnie acts like a jealous idiot, being outrageously rude to Mickey's new date and acting like an absolute cow. She encourages her rat boyfriend to make Mickey look stupid in public.
For reasons unclear to me as Minnie is obviously playing a lot of control games and on a power trip, Mickey still wants her back. Lucky for Mickey, the rat-guy turns out to be a rat-bastard. Mickey exposes rat-guy in public as not really being rich. (The horror!)
Minnie is then devastated that not only is her rich boyfriend not rich or cool, but her old standby isn't pining away and waiting by the phone for her.. Good thing Mickey is such an understanding guy, right?
Wrong. Mickey is a fool. Minnie's behavior was appalling. What strange lessons for children these were. Then again, I guess the couple did make it through another sixty years so maybe Minnie was just temporarily insane...
