Testing a Hard Hat

I’m not sure why they thought they needed to do this, but these workers are testing a hard hat. How best to do it? A whack on the hat with a broom handle! Why in the world would this guy volunteer to wear the hat?  This was not a test by professional quality control experts under laboratory conditions. At least I hope it wasn’t. I laughed before even watching the video, just from reading the description. (via Tastefully Offensive)
