In the neverending quest to see just how stupid people can be, we have a man, a fire, a soda bottle, and just a little bit of diesel fuel:

Five people, including two young children, were burned over the weekend, when a plastic bottle containing diesel fuel exploded while they were gathered around a bonfire, officials said.

My dad once tried to light a fire in our fireplace with (as I recall) about 1/4 cup of gasoline. He had us all stand back while he tossed in a match. The resulting fireball extended a good three feet out of the fireplace, roiled black smoke along the ceiling, set the smoke alarm off, and set the chimney on fire. My brother and I, who were I think maybe 8 and 10 respectively, had a predictable reaction:

COOL!!!

We were all sworn to secrecy, and it would've worked too except for the flames shooting out of the chimney, lighting up the whole neighborhood just as mom drove up. It sorta looked like a redneck Lighthouse of Alexandria. Fortunately the chimney was made of masonry, so all we had to do was hose the sparks down as they bounced along the roof.

From that day forward Jeff insisted we should start all fires with gasoline. For some reason dad didn't think this was funny.
