MacGyver was flat-out a show invented by potheads for potheads. Who else was really going to believe that pinecones could be turned into landmines? In addition to being the most unbelievable show ever, it helped to spawn a whole new breed of weed smokers. Everywhere you looked kids were trying to make bongs out of a pineapple, some shoelace, and a coin that their nana gave them for their Batmitzvah. While most of the pieces wound up as unsuccessful, every now and then you’d meet someone who came up with something brilliant. The photos you see below are worth showing off.
