Haha, I just remembered this, it's good.

I was walking and looking at some clouds, and one of them looked like a hand holding a bud in its palm. The cloud went behind a house for a few seconds, and when it reappeared it looked like a hand holding a joint, and there was another cloud right in front of it that looked like someone had breathed out smoke. For the rest of the walk I was convinced that some deity had just sent me a message that I was to be a missionary for marijuana.

Actually, I'm still a little convinced of that.
