I was just watching RotJ Special Edition when I caught another spoof. In the scene where Bousch (sp?) says she wants "fifty-thousand, no less" for Chewbacca bounty, Jabba knocks C-3PO over. They then pan over to Fett who strokes Rystall's chin then walks away. If you slow-mo that scene, you will see that Boba's jet pack already has the damage than Han does to it on the skiff. If I had the software to do screen captures, I'd post it, but I'm sure somewhere else can do this for me.
Has anyone else ever noticed this?
