Amazing how the dang battery terminals can come loose so easily! I was driving down to the hospital one time late at night and while driving down the highway, everything started flickering on and off and then my car just flat out shut off. The positive terminal had somehow managed to become so loose it just popped off of the battery. I had taken my little tool kit out earlier that day too...

Had to walk around some crap part of the city in the pitch dark to find something. Ended up finding a larger rock and pounded the terminal back on. Had to stop every few miles and pound it back on. Grrr.....
