A “Brady Bunch” reunion took place at an Ohio amusement park over the weekend to mark the 40th anniversary of the episode that took place there in the ’70s.

The famous episode was filmed at King’s Island, which is not far from Cincinnati. Barry Williams, Christopher Knight, and Susan Olsen showed up to celebrate with some roller coaster rides and also held four shows during their stay, where they answered fans’ questions and reminisced about the good old days.

The episode was one of the most popular for the show, up there with the family’s vacation to Hawaii. Audiences seemed to enjoy seeing the Bradys get out of their oddly-built house (can we say “no toilets”?) and into real-world situations.

“I think everybody, at some point in their life, wanted to be a Brady,” Williams said. “Their whole family seemed so perfect. They were so nice. I think it resonates with the child in all of us to want to be Brady.”
