Factual error: Kelso is wearing a t-shirt with Dirty Harry on it saying "Go Ahead, Make My Day". Sudden Impact was the first Dirty Harry movie to use that expression and that film didn't come out until 1983.
That '70s Show (1998)
1 factual error in season 5 - chronological order
Starring: Mila Kunis, Ashton Kutcher, Topher Grace, Danny Masterson, Laura Prepon, Wilmer Valderrama
Continuity mistake: When Kitty comes downstairs to give the gang cookies, she tells Eric that she picked out an outfit for him to wear on career day. He then turns and mouths the words "Help me." In the next shot you can see Jackie sitting on Kelso's lap when in the previous episode, she broke up with him. In the next shot she is standing behind him. (00:01:00)
Fez: Having sex with someone you work with is horrible. I don't know how Donny and Marie do it.
Trivia: In the fifth episode of the first season, Donna is left alone to babysit her little sister Tina. Both Tina and Valerie, Donna's older sister, were written off the show, much the same way as Richie's older brother Chuck, on Happy Days, or Laura's younger sister Judy, on Family Matters.
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.
Chosen answer: Danny Masterson is the one who screams "hello Wisconsin".
