Plant or animal?
Remember that? It was a game where they had a board made up like Zeppelin's Physical Graffiti album cover. Then they would play animalistic audio clip and the contestant had to guess if it was an actual animal or Robert Plant that made the noise. They'd lift up one of the window shades and reveal if it was indeed Plant or a baboon or cockatoo or something....
I can't describe it very well but it was maybe my very favorite bit from this show.
