Background[]
Summer arrives, school is out, and the boys go to Stu's Firework Shack to buy fireworks for the fourth of July. The shop owner, Stu, informs them that all fireworks have been banned in the state of Colorado after a kid from North Park blew his hand off with one. The only thing that he is allowed to sell are black snakes, but the boys do not buy them because they find them incredibly lame.
