Yoda will FART!
QUOTE FROM THEFORCE.NET
Okay. Here's how the scene was described to me. The setting... Tattooine (sic). Yoda and Chewbacca are together when the Clonetroopers are ordered to kill the Jedi. What does Yoda do? He grabs some mud, smears it on his face, jumps on Chewbacca's back, acts all stupid like his first appearance in Empire Strikes Back, and pretends to be Chewie's pet.
To further the deception, he farts. Yes, you read that right: Yoda farts.
