Well, the Star Wars Saga Blu-Ray release is coming up on us.
Uncle George decided to replace the puppet Yoda in Episode I: It All Goes Into the Shitter From Here with a CGI version to match the digital Yoda in Episodes II and III. io9.com's article on this has a nice pic comparing the muppet with the digi-version.
Now I love, love, love the Stuart Freeborn-created puppet used in The Empire Strikes Back, but boy oh boy, the puppet in Episode I is...just something, ain't it? LOOK AT THAT FUCKING THING! It looks like Yoda's dumb, drunk-n-hopped-up-on-painkillers, "look-alike" cousin.
