Three "Brady Bunch" cast members reunited at the Ohio amusement park King's Island over the weekend. That's the place where they filmed an episode 40 YEARS AGO. Barry Williams (Greg Brady), Christopher Knight (Peter) and Susan Olsen (Cindy) were there.
This was the episode where the dad, Mike, is presenting some architectural plans for the park to the directors, but the canister with the plans gets mixed up with one that has Jan's Yogi Bear poster.
Jan loses Mike's canister, and the family has to scour the park to find it before Mike's meeting ends. Once they find it, there's a classic sequence where they do a RELAY RACE to deliver the plans back to Mike in time. Watch it here.
