Don’t try this at home. Don’t try this at home, don’t try it in public, don’t try it in your friend’s semi-private back yard – just don’t try it ever. You will die. Probably. You will probably die and either snap your neck, killing you instantly, or break every bone in your body and WISH you had snapped your neck and died. Does being paralyzed from the neck down look like fun? I don’t think so.
Tl;dr: don’t fucking do this.
