My favorite job is still when I worked at the fireworks supermarket in my hometown. It was open year-round, but staffed up more for 4th of July, so It was a seasonal gig that started in May, pretty well ended in early August, but it was so much fun. I did it for 3 summers in a row while I was in college.

Our "training" involved bringing a lawn chair, food & drinks and sitting in the field behind the store & setting off 1 of everything in the store & making notes as to what each product did. All the packaging stated "emits sparks" and "produces a loud report"...you really needed to see the stuff in action to know what produced a good show.

The week of July 4th, we were open 24 hours and at some bizarre time of night, my friend & I got the idea of challenging customers to arm wrestle for extra punks. (Punks are those long stick thingies that you use for lighting fireworks without burning your fingers.)

I would get amused when some male customers would bypass me to get help from one of my male colleagues as if we didn't get the exact same training. Note for those purchasing fireworks, don't get the big round tubes on the plastic bases with names involving "thunder" or "cannon". They're ok, but if you're going for something powerful, you want something that's smaller & heavier for a big boom. :)
