It's great how this film follows a pair of halfwits as they make a mess of almost every situation they barge their way into, most films of this kind have a ringleader who thinks he has a great plan that will propel them above the rest of the deadbeats (like in Almost Human and Beast with a Gun) and they put a modicum of forethought into what they are going to do. But these two are just your run-of-the-mill eejits that are destined to be caught before they even begin.
Love the scene where they exchange the stolen weed for the guns, Paolo asserts the ganja is 90% pure, and the gunseller takes a bit of it and tastes it for authenticity!
