It may just be me, but stuff like that didn't work on me back when I was in shop. I had good teachers who instilled proper tool use which I think was much more helpful.
I do remember one of the 'scare' movies 30 years later, however. It was a guy who got metal chips in his eyes and was blinded. Throughout the movie he folded and unfolded a walking cane probably at least a dozen times every time he moved, to show us what we could expect if we weren't careful. But the part that sticks with me is him saying is 'my safety glasses were in my pocket, lot of good they did me there'. I still say 'lot of good they did me there' for all kinds of things, but I don't think that's what I was supposed to take away from the film.
