Not gonna lie, when I was a kid, I tried this.
Ok, so it wasn't 10 stories off a building, it was a few feet off of my bed.
I had seen Mary Poppins when I was a child and thought "Hey, I could do that!".
Needless to say, it didn't work jumping off a high bed, so I was smart (and used common sense) and didn't try it off of a building.
This kid, however, was not so smart.
