Ill start...this is a good one - its not the cars fault, but still.
I left my feeler gauge on the radiator/head bracket and forgot about it.
Started the engine, feeler fell off, hit the fan and BOOM! lost an inch and a half off the end of one of the blades and the feeler guage looks like a cartoon exploding cigar.
thanks brain.
