Who Wants to be a Millionaire viewers were gobsmacked by Richard Madeley's blunder.
The veteran broadcaster appeared on tonight's celebrity edition of the popular game show. The 66-year-old was raising money for Cornwall Air Ambulance and St Frances Hospice.
Jeremy Clarkson hosted the show and was baffled as Richard committed a series of gaffes moments into the episode. Richard first walked to sit in Jeremy's seat before he repeatedly referred to the host as his predecessor, Chris Tarrant.
