Why anyone would allow their crotch to be destroyed by a tire from an 18-wheeler is beyond me.

This guys starts off the video by saying, "this is the most extreme thing I've ever done."

I would like to correct him by saying that this is the dumbest, yet smartest, thing he has ever done.

It's dumb for the obvious reason that his man parts are getting crushed by a huge flying tire.

It's smart though because the odds of this guy being able to have kids have decreased significantly.  That means that he can't pass on his knowledge or supreme decision making ability . . . which is a good thing.
