The Brain as Explained by John Cleese

As Robert Krulwich explains,

You've met them, I'm sure. People who are so learned, so scholarly, so deeply invested in what they're doing, that you can't understand a word they're saying — well, maybe you catch a familiar word or two, but the gist? No. They seem to be speaking a language near yours, like the Sims in "SimCity." The sounds are right, but the words are beyond you. In this video John Cleese gives us a short introduction to the anatomy of the brain. It's complete nonsense. There is only one complete sentence. It comes at the very, very end.

And he highly recommends turning on the closed captions the second time you watch this because they are even more nonsensical. (via Ed Yong)
