Celador in association with Thames for ITV, 5 September to 13 October 1989
'If this show was a gameshow, what gameshow would it be?' 'Well, it would be PSI, wouldn't it?'
And that, my friends, sums up PSI nicely. Two teams of celebrities would try and guess who various mystery celebs would be if they were, say, a type of cheese, a Laurence Llewellyn Bowen style house furnishing, a type of light bulb whatever. And that was it really.
It was based on a popular (at the time) board game, but if you were ask 'If this show was a gameshow, what gameshow would it be?', an equally acceptable answer would be 'Celebrity Intuition', because that's what the show changed its name to after about two series. No one knows why. Still, we're still waiting for Stephen Leahy to come up with 'Celebrity Table Football' or 'Celebrity Kerplunk'.
Hosted by Chris Tarrant, the latter could be fab as a celebrity can pick a straw and he can go 'is that your final decision?' or 'confident?' and when all the marbles came tumbling down he can go 'I'm sorry, you've just lost 14 marbles'.
Based on the board game PSI, which stood for Psychology Slander Intuition. The game was invented by Steve Knight, later one of the team behind Who Wants to be a Millionaire.
Crazy Comparisons, basically the same show under a different title.
