When I was quite young I knew there were two kinds of snow: white and black. I didn't know where the black snow came from but I knew where to find it -- alongside the road. One day I said to myself (because I also thought I had to explain my actions by thinking out loud, like on TV) that I was already familiar with the taste of white snow but not black snow. So I scooped up a handful and put it in my mouth. Needless to say, it tasted just awful and I never did that again!
