Have a funny story about the POP where I worked we had a driver that was VERY accident prone. She had the hose on WHAT EVER side of the turbo blow off it caused power loss and TREMNDOUES amount of black smoke and She didn't see it but the Pyro just about bent the gauge pointer. At our safety meeting She proudly stood up and told her story about how great a job she did at saving the truck from sure disaster. She went on to talk about the LOUD !! POP !! and that is when SHE knew something had gone wrong. I started to giggle and the safety guy said you have something to share BIG??? He insisted so my comment was that the LOUD !! POP !! SHE HAD EXPERIANCED WAS WHEN HER HEAD, NECK , AND SHOULDERS CAME OUT OF HER A** The big boss ( a good friend ) had to do something so he gave me the next 2 days off (he knew they were my regular days off anyway) :-laf
