In 2005 after the company had just got back from Fallujah, we had an epic war of exploding cigarette charges amongst the smokers (about 60% of the Marines).
It was constant. Dudes were trying to disract each other while a third party sabotaged a smoke. Guys were physically inspecting each cig they took out before they lit it. Obviously the charges weren't large enough to do much, but they would blow the end of the cigarette off if you used a couple.
One afternoon as everyone was gathered around the company office (and the smokers were smoking), a kid's smoke blew up and we all had a good chuckle about it. One of my fellow SSgts was out smoking with them, and he went on a tirade about professionalism and not messing with other people's stuff, and how childish it is to put exploding charges in cigarettes.
^ While he was in the middle of his speech, he lit a cigarette. No shit as soon as he shut up, he took a drag - and that frigging cigarette of his blew up in his face.
That was probably the hardest I laughed between '04 - '06.
