O tannenbaum!

I am out of the loop. I had no idea that the upside-down Christmas tree was the hot trend of the season. It was mentioned in a magazine, and naturally, I went to Google for the dirt. It just looks weird to me. But, I can see one advantage in it being upside-down. Archie wouldn't think it was a real tree and want to mark his territory, if you know what I mean. But where do you put the angel?
