One of the best I ever saw was when we were painting the ship, usually used rollers, but this new chief wanted us just to spray, OK he gets this sprayer that goes on top of a 55 gallon barrel of paint, ok cool. We were in Marseille France at the main naval base well he hooks up the air. Boom the freaking barrel exploded paint all over the place, cars, their ships etc. Well a ship has low pressure air 100 psi and high 2500 psi. Guess which one he hooked up to? Freaking funny as hell.
