So many to choose...
Ok...
When I was in high school, I was always broke. Since I didn't want to always be mooching off my friends, my only option was to mooch weed from strangers.
I would hang out at a park or a concert or wherever really.
When I'd spot a circle, I'd walk up to them and say "Excuse me, I'm with the Cannabis Quality Control board. I'm going to have to test your weed." They would usually laugh, and pass it to me.
After it was finished they would ask, "Did we pass?" and I would answer...
"It's not a pass or fail thing, we just compile the results for statistical purposes. Thank you for participating."
I met one of my favorite dealers that way.
