I got my name from working in underground mines many years ago (I'm a certified geologist by trade). - I had a dangerous job, I had to climb up into difficult areas in the mine to clear them of debris and loose rocks, to make it safe for the miners. We used to call the miners who worked with explosives ‘powder monkeys’. Some of them started calling me the spider monkey, because I could climb into difficult areas where no one else would go. - From there, one of my mates started calling me Monkey Marc, and I guess the name stuck.
