Ok, thought of a small one..
When driving the SHO one day, the check oil light came on...but I was in a hurry going somewhere but I was near the house.
I pulled up to the garage, opened the hood (car still running) and put about a half a quart of oil until I was ready to change it.
While pouring the oil, (without a funnel) some went onto the exhaust manifold and promptly caught fire. Lotsa wires up front of the SHO, plastic fans, etc...
No fire extinguisher at my house.... so I did the next best thing... grabbed a solo cup and started dumping water as fast as I could on it from a nearby faucet (no hose in sight)..
It finally went out and the next day I bought a good fire extinguisher...I was going to be welding the floor panels in the truck that weekend )
