This guy is an absolute idiot. His first mistake is making his own firecracker, his second is to go back to it after it failed to explode, his third is sticking it in his mouth like it was some strange brand of cigar.
And yes, the inevitable happens.
I’m guessing I’m not alone in having been taught how to safely use fireworks. As a kid, it would happen every year before Bonfire Night, with parents and teachers both giving dire warnings as to the danger of handling fireworks.
I’m guessing this guy was absent on every occasion, as it’s the only explanation for his stupid behavior. Still, it makes for a funny video. So there’s always a silver lining.
