That '70s Show star Debra Jo Rupp was initially clueless about the time period of the series.

While speaking to, Entertainment Weekly, Rupp and her co-star Kurtwood Smith explained why she didn't initially know That '70s Show took place in the 1970s. Rupp, who played Kitty Forman on the show, blamed her confusion on the original title of the series, "The Kids are Alright." "I think I was in a bit of shock because I did not realize that this was set in the '70s until I saw the appliances on the set," said Rupp. Smith subsequently joked if the actor believed they were having a costume party.
