When I was in college about 30 years ago, I once left the headlights on all day while I was at work and then tried to roll start the '72 AMC Gremlin down a long hill but I didn't realize I had the key in the accessories position instead of the run position. Since it didn't start all the way down the hill, my buddy and I hooked up jumper cables and when I went to start it it, the raw gas that had been pumped through the engine into the muffler exploded, blowing the muffler to pieces. It sounded and felt like a bomb going off. The worst thing was that it I had borrowed the car from another friend and it wasn't even mine.
The good news from this was that when I offered to pay for the damage, my friend sold me the car for $100. It was an old beater but ran great and I really needed a car since my '67 Triumph GT6 needed a new transmission and wasn't driveable at the time.
