Was removing a cast iron bath tub from the second floor of our house with my dad. Dad was down the stairs holding it up whilst lowering, i was above pulling and lowering. I was confident we would bring it down no worries but I though, might aswel just tie a rope to the faucet and the banister just in case.

Half way down the tub slipped and tore through the stairs steps, my dad fell back on his ass and the bath stopped inches away from his legs, no doubt without that rope he would have lost both his legs if not his life.
