Remember "Liquid Television" on MTV? Specifically, I was wondering if anyone can identify some anime I saw.

2 parts to this:

1. one of them featured a futuristic race track in which drivers circled a stadium and horrific crashes were common. One driver died while driving and his brain continued to live and operate the car even though his heart had stopped. anyone know the name of it?

2. the other one was called "planet jackson". it was some anime with new dialogue dubbed over the top and was hilarious. it featured a little dude jumping off a waterfall yelling "naked time!!!" would just like to see this one again.
