I once knew a man who accidentally blew up his living room and nearly himself also by lighting a fireplace when he didn't know that other family members had already added lighter fluid to the wood. I'll never forget how his 7-year old son came into the room to find his smoking eyebrow-less father flung backward behind a blackened couch and started singing "happy birthday to me".
Then of course was the time my father and mother got drunk at their friend's party and accidentally burned down his 120 million dollar worth marijuana crop. For some darnedest reason, we moved out of the area soon afterwards. ^_~
