A “fireworks mishap” happened to a coworker a couple decades ago. He threw a Fourth of July party at his house, and somehow a sparking roman candle ball got caught inside his sneaker and severely burned his ankle/heel/Achilles’ tendon. He came into work on crutches for quite a while after that.
I honestly don’t know if he ever came to the personal realization that beer and fireworks don’t mix. Since it seems that most people who make those kinds of decisions tend to blame them on other people for being drunk, instead of thinking “hey, I gave that guy a lot of beer and then this thing happened”, I doubt it.
EDIT: TBF he was a Wisconsin resident at the time, and I’m pretty sure it’s required that every party guest blows at least a .08 before going home.
