One of the funnier things with me happened in Vancouver outside a smoke shop (are those still open up there btw?), where you can bring weed in and smoke, but it was still illegal to buy. Crazy laws. Anyway, we parked and were trying to score a little bud across the street which was crawling with sketchy, homeless looking dealers looking to sell herb to out-of-towners like us. One particular sketch ball who looks like he hasn't slept in a week rolls up on a bike, we chat and we start our transaction. He's paranoid as hell, looking all over telling us to watch for cops, etc. As we're handling things, a couple friends of mine were just getting out of the car. They open the car door, and just as he hands me the bud, for some reason my car alarm starts blasting out of nowhere - loud horn blasting, lights, everything. Dude basically shits his pants he jumps so high, gets back on his bike and pedals away furiously without taking our money. Total accident, we never figured out why the alarm went off. Walked across the street and smoked his weed, laughing our asses off at our good fortune (it wasn't a huge amount, but still funny.)
