Had one at my dealer before I worked here, picture this, we're right next door to a hotel, and right off the I-80 freeway, there's some sort of fire fighter conference going on at the hotel, and one runs away in the back lot, smokes out the freeway and everything, bunches of firemen come over to see what's going on, turns out some guy from the EPA was on the freeway, so he came over to see what was going on, he tells my manager "you need to shut that thing down" manager tossed him the keys to it and said "here's the keys, you shut it down" I guess it finally grenaded!
