Why Does Yoda Speak Backwards?

 According to George Lucas, "Because if you speak regular English people won't listen that much. But if he had an accent, and it's really hard to understand what he's saying, they focus on what he's saying."

According to Lucas, Yoda is the philosopher of the Star Wars saga

By far Yoda is the most beloved of the Star Wars characters, the old, small, and cuddly Jedi master is number one with the 8-13 aged children. 

At 80, Lucas makes few public appearances. Long live Yoda.
