I didn't do this, it was someone else. My stories about myself tend to not be as entertaining.
Years ago back in high school I had auto body, me and my buddy were sent to auto tech which was a separate building from ours across the yard (close enough that we can bug each other by yelling, but far enough that we have "leave" class to do so even if were both outside). While anyway we were both sent to auto tech to get some tires put on a set of rims, and during this time one of our senior students (2nd time taking it, despite passing it prior if I recall correctly) was welding on a motorcycle gas tank. There was one slight problem it was still filled with gas because he was trying to cheap and didn't want to waste gas as it was at an all time high back than. So he thought he be fine if he just left the gas cap off and than proceeded to weld on the tank, without gloves, with the tank BETWEEN his legs while sitting on the worlds cheapest/flimsy plastic chair. Now as I said before I wasn't there, but when me and my buddy walked back into class we saw every single student surrounding him cussing him out in a mix of English and Spanish (there isn't enough cuss words in English for his level of stupidity) and I asked what happened. So I will give you the more politically correct and fully English version of his reply which would be along the lines of this "Freaking idiot over here welded on a gas tank WITH GAS in it and dang near caught the building on fire. Flames almost hit the roof (probably a good 30ft to roof), and he almost ensured he never have kids again. Freaking idiot!". (The real unedited reply is far more entertaining, but would probably get me banned in a heartbeat)
But his story is not over yet. The very next day he was back at it again with his new found knowledge that gas and fire don't mix. So this time he decided to empty the gas tank, sit in the same seat, same position, and not wear gloves again. And of course the gas tank in the same position as the day prior. But this time he decided he wasn't going to weld on it, but use a gun we have which basically welds a nail onto a metal surface so we can attach something to it to pull out dents. It doesn't sound too bad yet, empty tank, light welding, just poor safety. But I am leaving out 2 little details, he just emptied the tank and didn't clean it out and he put the gas cap back on. So he goes about his business using the gun to weld nails onto the tank when all of a sudden I hear a very loud explosion. At the time I didn't know he was doing this or else I would have stopped him, but I was in a different part of the shop 20ft away with no view of him. But I can tell you I knew who that explosion was from the second I heard it, I also knew that with where I was mixing up bondo I was in the safest location in the shop from where I heard the explosion. In order to get to me, it would have to pass through and old 1930's car that used a lot of thick heavy duty metal everywhere, 2 solid wood doors with steel plating, as well as various other things to get to me. Since I heard no screaming or anything that would lead me to believe anyone was injured I figure I wait a good 10sec to see if he manage to blow something else up, or hear instructions to run if there was a danger of more explosions as I was already in a decently safe place and all exits out lead me closer to danger. So eventually I walked over to check up on him, and saw the same thing as the day prior with everyone standing around him in a circle cussing him out in multiple languages. In between his legs was the gas tank. It gave way at the bottom on both sides and the steel was bowed out a good 3-6in and somehow there was no shrapnel and he wasn't injured at all. The teacher walked in and took a look at him and the gas tank and in a sarcastic/excited/childish voice said "Do it again! Do it again!".
After everyone was done with him, he tried to sell the gas tank to us...
