"The Weakest Link" host Anne Robinson

With several celebrity editions under its belt (including an '80s TV-stars special, a Survivor special and an all-comedians episode), the show will soon showcase a team of well-known contestants of mass appeal: the original cast of The Brady Bunch. The six Brady children--Barry Williams, Christopher Knight, Mike Lookinland, Maureen McCormick, Eve Plumb and Susan Olsen--and TV mom Florence Henderson will appear.

So will an eighth obscure cast member--Robbie Rist, who played a Brady cousin.

The appearance marks the first time the original cast has been reunited since 1980, when the TV movie The Brady Girls Get Married aired. As for The Weakest Link, the winnings from the show will be donated to each players' chosen charity.

The special episode airs in mid-September.
