One school day, durring the 10th grade year at lunch after bird watching with the group, Greg wondered "How can you tell the potency of the weed you smoke?" After awhile in silence Greg realized there was a mathematical equation that you could use to tell how great the weed was. He finally came up with the equation while sitting in front of McDonald's with Braiden while Joe, Bill, Zach, Gabe (and possibly others) went inside to get some eatz. Anyways... He told this to Zach and Joe and it made sense to them. But then Greg forgot the equation for several months afterwards.
