Did the same thing with my Mom's safety razor when I was 4 or 5, although in my case it didn't totally stop the stupidity. A couple of years later I had the "just because the range-top eye is black doesn't mean it's not hot" experience, and a few months ago I had the "it's best to not put one's thumb behind the slide of a pistol" experience.
