Call My Bluff was necessary viewing if you were an intellectual-type interested in learning the derivation of words now deemed superflouous in modern day society.
I liked it because it had a bell in it that went "PINNNNNGGGG!"
Robert Robinson presented this when I used to watch it, and basically all that happened was that a word appeareed on the board behind the presenter and the guests of one team had to read out a possible meaning of the unusual word.
"And the word is..... (*PINNNGGGG!) ..... Flobmyre."
guest 1: "Well, a flobmyre is a squelchy swamp"
guest 2: "Flobmyre means to sag to one side in limpness"
guest 3: "Flobmyre is an onomatopoeic word to describe how a cat lands after being startled off a wardrobe."
Then team 2 had to guess which of the members of team 1 were telling the truth.
It sounds weird, but it's ace.
