20th Century History Teacher

He stands at the front of a classroom lecturing about the 20th century as if it were ancient, murky history—which, a thousand years on, it is. Confident and utterly wrong about the details, he delivers his garbled facts with the flat authority of someone who has never once doubted himself.

The joke is structural: everything he says is slightly, hilariously off, and Billy West plays him with the dry, unbothered cadence of a teacher who's given this lecture a hundred times and stopped caring whether it's accurate. It's a quick, efficient bit of Futurama's favorite trick—flattening our present into someone else's dusty trivia.
