Sid In Toy Story 3
I just realized that Sid Phillips - the evil kid from Toy Story 1 - makes a brief appearance in Toy Story 3. He is now grown up and working as a garbage man. Sid appears twice in the movie. First, when he comes to pick up the trash from Andy's house and second, right after Woody and the gang escaped from the incinerator near the end of the movie.
Although I can't get a clear good look from his face cause he was wearing goggles and a big set of headphones, Sid is identifiable by the same black T-shirt bearing a white Skull that he wore during the first movie.
Yup, that's him!
