Revealing mistake: The scene where Donna and Eric are running towards each other, each shot of Donna and Eric individually shows them running past the same umbrella and surfboard. They were using the same section of the beach to shoot both Eric and Donna running.

Question: Who exactly shouts, "Hello Wisconsin!" at the end of the opening credits? I've long assumed it was Topher Grace, but it sounds as though it could be Danny Masterson or Ashton Kutcher as well.
