like, I appreciate that it’s a joke at this point, Bing’s weird attendance of med school, but also: that’s not really how you fill plot holes. Pointing at a thing and saying “this is a thing, we know it’s a thing, and at this point, it’s a pretty hilarious thing, but we’re not ever going to explain it because it’s past the point where we can explain it, so let’s just have a laugh and pretend that’s enough” is a shitty way to cover your narrative failings. It’s like using a reference as a joke in an of itself without writing a proper joke with a reference included in it–it’s not funny just to refer to the thing, you’re making the thing do your work for you. Is it funny, yeah, but does drawing attention to the holes in your story endear you to me? Not so much. It’d be a hell of a lot funnier if the joke was grounded in some kind of rationale.
