It's nice after years of human bashing "oh aren't we awful we're causing global warming", "god we're horrid all this war and greed and killing, "no one's faithful...Ashley cheated on Cheryl again" stuff, to hear someone celebrating humans for the marvellously clever things that we all are. We can make cars and toilets and the internet! Yay us! That's why I like this advert for BBC knowledge. Its also really cute. Aren't the animators great! Yay us again!
Look here's another cute one. Apparently they're by Three Drunk Monkeys.
