What does Darth Vader do on his days off? In this video, he enjoys a pleasant one-wheeled cycle through the streets of Portland (of course) while providing his own Imperial March theme music (after an extended bout of the Star Wars main theme). So which is more difficult, riding a unicycle with a bagpipe in your arms, or blowing into the pipe while wearing a Vader mask?
Edit: Changed title because it was too distracting — it's the Star Wars theme first, then the Imperial March. I just think it's more fun that he plays the march.
