Darn
It was probably a year ago that I saw it, and my recollection's awfully vague. I'm not sure I even remember a cartoon. I guess I'm not competent to comment.
I seem to recall, with similar vagueness, that there was a dubbed voiceover during the classroom scene (or maybe I'm just responding to suggestion, because it's such a common device). Something like that's not likely to be mistaken for an actual recording of Bush's thoughts at the time, and I'm sure people understood it as a device for making a point. It's a common satirical device, seen often on The Daily Show and SNL and many other spoofs. I don't really have a problem with it, if that's what you're asking.
