The Weakest Link - NBC All Stars (May 26, 2002)

Hoping to win money for their chosen charity, eight celebrities risked embarrassing themselves on national television.
General knowledge is hard.
The competing All-Stars (in order of introduction) were Dennis Weaver, Erin Gray, Ed Begley, Jr., Vicki Lawrence, Davy Jones, Raven-Symone, Nichelle Nichols and Dirk Benedict. Anne Robinson hosted.
Watching this now, 18 years after it first aired is painful - especially if, like me, you are a Nichelle Nichols.
Nichelle's dementia wasn't diagnosed until 2018 but I wonder if she wasn't already feeling the effects.
Although, to be fair, Nichelle isn't the only celebrity having difficulty answering the questions.
