I don't really like pot anymore, but I used to love it.
One memorable 4/20 I was riding shotgun in my buddy's car, we were smoking a joint. I went to hand him the joint, and we fumbled it, and it dropped under my seat. So of course, I quickly bent down, searching for it... I was crouched over, my head as low as it could go, reaching around with my hands, and suddenly I heard a loud *HOOOOONNNNKKKK*. I looked up, and we were driving in the opposite lane with traffic coming at us, almost going off the road into the ditch at that point. The driver had decided instead of driving while I looked, we would be better off with two guys on the joint hunt and so he had been bent over in the car looking too. That was the last time I rode in a car with him.
