I was out in the garage taking my shift knob off and in the middle of it I heard a very loud pop (like the sound a light bulb makes when you drop it and it breaks, but 10 times louder) and saw a flash of white light in front of my car. The key wasn't in the car, nothing was on, just twisting on the shift knob. I had really bad thoughts wondering what that could be, but everything works.... all lights, engine starts, a/c runs... nothing seems amiss. And nothing in the garage is amiss. I don't know what the hell it was, but it's probably going to bite me in the a$$ when I least expect it.
