Near the start of the movie , when Buzz and the toys are crossing the road to Al's Toy Barn, Mr. Potato Head steps on some gum and his foot comes off, at the same time, a big truck with a pipe on it suddenly stops and the pipe comes off. Mr. Potato Head is in the middle of the pipe and then the scene goes back to Mr. Potato Head finally getting his foot free. Then the scene goes back to the pipe... and Potato Head is at the edge of the pipe. What??? This is a big mistake, and it is so obvious, but funny! (How could the producers miss it?)
