TITLE: What is your best "WHEW that was close" moment?
POST: When i was 17 i believe, i use to climb out my bedroom window onto a mini roof of my house to smoke cigarettes to avoid my parents catching me.  One day it was snowy outside, and this mini roof had maybe a 1 inch coat of snow.  I went out in flip flops (GENIUS), and lit up my cig.  I went to move my foot and slipped, proceeded to slide down the whole roof, and literally stopped in a seated position with my feet dangling off the roof.  I look down and realized if i had kept going, i probably would have split my balls open on the fence 20 feet below or something.  I would have been seriously injured no matter what.  WHEW that was close! Needless to stay, i stopped smoking cigarettes on my mini roof.
TL;DR: 
smoke cigs on 20 feet high mini roof, slip and slide down roof in snowy weather and somehow stop just before falling off the edge.  stopped smoking cigs on the mini roof
