One time in college me and my two friends were walking up the street to where my car was parked. Since we were already high, and we went out almost every night, I led them down the wrong street at first. I realized where my car was parked and we set on to where my car was really parked.
When we all got in, I realized that I had lost the spliff. we walked all the way back to our dorm and rolled another. We drive around and smoke the L, then I parked on a different street a block away. We were joking around about how I lost it, when I realized I could be using this time to actually be searching for the lost joint. I look down right at the ground and saw it at that moment, so I call out to my friends 15' away, "hey, I just found it!."
They were in disbelief and thought I was joking, but I said breezily that I was serious and I showed it to them - their faces melted away.
