No not the characters themselves, the point of view. Like if they show you an opening sequence where the first thing you see is Bart Simpson spelling out by rote a line that is funny and does change episode to episode, then Homer Simpson fumbling a stereotypical regulus, like is it supposed to be radium, which does glow green, or more likely uranium, which is what powers a nuclear plant? It doesn't matter. You trust that someone who just told a funny joke will tell another funny joke, so you laugh without thinking it over. Humor sandwich.
