lol, my mate was driving his smart car and noticed that the rear corner brake was binding - he waited until he got to a service station before he pulled over, and because the friction had built to such a point, it had set on fire. his first reaction was to get on his hands and knees and try and blow it out, lol. then when he saw sense, he ran into the service station restaurant, ran straight into the kitchen, grabbed a pan filled it with water, and ran back out!
for this very reason, i always carry a fire extinguisher in my car - i figure out, it might not put a big fire out, but it could put out any flame on me
