 The man was showing off when he put the firework on top of his head, according to people who were there. His wife implied that, well, it was a block party, and he was, in fact, drunk at the time when he did it. And she said that they had observed her husband putting the firework on his head, but also believed he was just not going to ignite it, which, in fact, he did ignite it, and it went off, and, well, he's dead. Oh, gosh. There you go. Oh, man. And there you have it.
