You know, all this talk of overanalyzing everything has prompted my memory.
Most of you know that I used to be so obsessed with the cartoon series Courage the Cowardly Dog, and as that show progressed, it got just a little bit darker each season, and there's one episode that particularly stands out from the show's final season, called "The Mask".
In this episode, which was a take on old-fashioned noir films, a lady dressed in a large mask and a white cloak, named Kitty, arrives at the Bagge farm, where she tells them her "life story": for starters, she came from "the wrong side of the tracks", but her life had taken an even more depressing turn when her "closest and dearest friend", Bunny, fell in love with a gangster named Mad Dog, who didn't approve of their close friendship, and basically chased Kitty away from her own life, forcing her to leave behind her home, her life, and her friend Bunny. We even see that not only is Kitty depressed without Bunny, Bunny is also depressed without Kitty, which angers Mad Dog, after all he's done for her (supposedly) that she still only thinks about Kitty. Though it wasn't his original intentions, Courage ends up on a mission to rescue Bunny from Mad Dog's control, and bring her and Kitty back together; Courage even learns from an "informant" (basically a mutual friend of Kitty and Bunny who runs a diner) that Mad Dog is "the nastiest piece of jealousy who ever lived", hence why he disapproved of Kitty and Bunny's friendship. After some wild action, with Courage luring Kitty away from Mad Dog's joint on foot, while Mad Dog chases after them in his souped-up cadillac, Mad Dog is injured by an oncoming train, after Courage steers the car onto the tracks (luckily, cartoon violence only results in Mad Dog in a dopey daze on the front end of the train); on the final car of the train happens to be Kitty, no longer in her mask or cloak, calling out to Bunny, who quickly chases afterwards. Kitty pulls Bunny aboard, and the two of them are ecstatic to be reunited, and plan on spending the rest oftheir lives together forever.
Now, like Ernie and Bert, this could be argued that Kitty and Bunny being just friends, and nothing more, however, it really was the creator's intentions that Kitty and Bunny were to be interpreted as more than just good/close/dear/best friends... in fact, as an adult, and knowing a few more things about life and such, one can see that Kitty and Bunny do act more like lovers than friends.
That said, despite the facts that they live together, sleep in the same room, and all that jazz, never once, in over forty years, have Ernie and Bert ever acted like lovers; as many people pointed out, it's more a matter of them being like the typical television Oscar and Felix-esque odd couple, which not surprisingly, is a concept that's been around for eons as well.
