I remember the time when I was like 9 or 8 yrs old, I went to my little cousin's house and I saw that there was like a box, crate thing near the edge of the matress in their living room. And my dumbass decided to go in the box rock back and forth, and I fell backwards and landed on the edge of their stairs on my head. And thanks to the edge (that was made of concrete) not being sharp at all, there were no blood, cuts or shit happened. :)
