Jeb Corliss " Grinding The Crack"

I normally don't post other people's work.  However, my twenty-year old son showed me this video on Youtube several days ago and I've watched it at least three dozen times since then.  It's utterly insane.  Crank up you speakers loud when you watch it.

My son who thinks he's invincible wants to try it.  The bad news is that I do too.  My wife's reaction?  She thinks it's obvious that this guy isn't married.
