Two spaces vs. one space?

^^Unless you're two you don't have to worry about the astrological sign thing - completely debunked.

I was always taught that the end of the series comma (rainbows, ponies, sunshine, and unicorns are everywhere) was strictly personal preference. I honestly am 50-50 as to how I use this one.

And I want to see the German punctuation. Are they speaking PA Dutch to go with it? (example: "Throw me down my purse.")
