There was an awful part in a recent Simpsons episode (probably post-2010) where Bart and Lisa are at a junkyard I think? But they find an old television set, like those CRTV's everyone had in the 90's, and most of this show's existence, before everyone got flatscreens. Lisa says something like
>it's like a tv, but...it keeps going
as she feels the not-flat sides. Yeah, they actually make that joke. They've never seen this kind of TV before.

Does anyone know what I'm talking about? What episode/season was it?
