I'm not sure if this belongs in the 'Stupidest decision...' thread but, personally I find this story to be pretty funny.
Anyways, so I'm at a buddy's house, out in the ventilated garage, extracting up some honey oil. I was using the 'Honeybee Extractor' and some butane, of course. Everything is going along swimmingly, when another one of my drunkass buddies staggers in, looks at the honey oil and says 'Lemme get a good look at that'. He proceeds to pull out a lighter and spark it. I said something to the extent of 'Holy shit! No!' before the immediate area around me burst into flames. I tried to smother the fire on the honey oil pan with a cloth, which then also burst into flames. I throw the cloth away, and it happens to land on an Oxy-Acetylene rig. My buddy sees this, stomps out the cloth fire, and then starts rummaging around in the pesticide bottles in the garage for some reason. At this point I used a beer to put out part of the fire and we stomped out the rest. After we nearly blew up the garage, another buddy comes out and asks 'What was that big flash?'. It was some seriously funny stuff.
I have a lot of other stories, but I prefer to verbally tell them rather than type them. Something's lost in text.
