General "Did you Know?"s

[CosmykTheDolfyn]

This is Yoda's origninal concept art:

He was nearly a Smurf.

Also, speaking of Yoda, it's unknown whether he has 3 or 4 toes, as how many he has switches between movies.
George Lucas has refused to ever say what species Yoda is or where he came from. He has also stated his disapproval of placing other Yoda-like creatures in certain Star Wars novels and games, stating that Yoda should be unique. His closest to an explanation of what Yoda is is that he is the love child of Kermit the Frog and Miss Piggy.
Edit: Also, this bizarre Easter Egg is on the Star Wars Episode III DVD, accessed by a pausing the movie at a specific place (certain frames of the THX logo at the start) then input a string of channels through the DVD player.

Yoda has them moves.
