 It's an urban thing. Story two, 4th of July aftermath of stories that people have been killed or injured with fireworks continues to grow. A 41-year-old Florida man injured after igniting a large firework in his butt during the 4th of July party. Apparently the man was wearing an Uncle Sam suit when he came out to his party goers with a firework protruding from his backside. He lit it and watched as it exploded.
