It might be hard to follow the dialogue on this 1993 episode of some Japanese TV show with Ayrton Senna, but you immediately get how humble Senna is, how cool he stays, and how goofy he's willing to get.

You can watch whole episode in four sections: Part 1, Part 2 (featured above), Part 3, and Part 4. Watching him crack jokes, bet the other drivers to race in their underwear, and happily dice it up in a kart with nothing to gain shows that there was much more to the man than raw speed.
