If you're about my age, you grew up with an endless series of school science movies, narrated by soporific baritones, with muzak/porn 70s soundtracks, introduced by professorial types in their studies. Disney did them, everyone else did.
In a wonderful homage to this, Sega has made an ad site for their game "Full Auto" called Sega Labs.
They have the whole thing down, even the slightly out of sync sound and bad cuts. Plus, explosions. What's not to like?
