Have you ever taken a really good look at Yoda’s upper arm development?

No wonder he stuck to training; he’s as boneless as a Mcnugget.
That picture is taken from a fun article about demystifying Star Wars at CNN.com, an article in which I also read the following about Yoda:
“We thought, ‘Maybe if we trained a monkey, in an outfit, and then animated the lips…?’ ” Kershner said, his voice rising decades later over the old frustration.
Imagine it! So many missed opportunities.
(Star Wars came out on DVD a week ago, and this is all the space I’ve devoted to it. Are we not proud? Is this not a sign of some sort of latent development?)
