It's July 4 in the US, which means people have an excuse to blow stuff up. Nay, it's encouraged. Just as long as you're not doing what the idiots in this video are doing.
Setting off fireworks under someone's chair, pointing them at your friend's face, igniting explosives near your crotch and making a big boom indoors? These are all examples of what not to do. You could lose an important extremity, like a finger or something worse. [The Awesomer]
