The glory and wonders of Genocide

So remember that episode of Gumball where Darwin becomes basically safety Hitler and calls the Cartoon character to get him to not use dynamite. I have an existential theory about that episode, because the Cartoon character was able to pick up the phone pretty much instantly, I have theorized that the cartoons in the Gumball universe are all just live streams of real “people” (not sure what else to refer to them as) doing stupid shit.
