Damn, what a dumbass! We as taxpayers are thankful he didn't injure himself to the point of needing 24/7/365 care in a nursing home (aka Warehouse of the living dead) because of his stupidity. Now for his next trick he'll allow his buddies to kick him in the nuts to prevent him from spreading his defective genes to future generations...we can only hope.
I forget which class it was, but some engineering class in college where the instructor was talking about tempered glass. He said they run it through an annealing step after tempering because the NTSB (or whoever sets car safety standards) determined the glass was harder than a human skull and your skull would tend to crack before the glass would break. Too bad we didn't get to see this young lad run the experiment to completion.
