Alcohol and fire. Welcome on their own, but together, oh, they're trouble. Check this video from the 1981 Indianapolis 500, when Rick Mears and his chief mechanic caught fire ... invisible fire!
Hat tip to our good pals over at Deadspin for this one. They appear surprised that there are invisible fires (or, as LOLCats would say, INVISABUL FIRE) in racing, but I think we can all remember at least one other similar incident, can't we ... ?
I'm going to use the "invisible fire" defense to get out of everything now.
