A little off-topic, but hey, I feel like typin'.
Once I was playing with one of those metal matchsafes, you know the old cylindrical Marble brand ones with the rough striking surface on the outside. I had it full of strike-anywhere matches. I pulled a match out and didn't screw the end back on the matchsafe completely. I struck the match, and somehow a bit of the burning head went flying back inside the matchsafe. Before I knew it, I had a little mini-bomb in my hand that I quickly got rid of.
Morale: Screw the lid back on the matchsafe before striking.
