You Must be Joking
BBC1, 18 April to 20 June 1981 (10 episodes in 1 series)
As far as we can tell, an attempt to justify TW's salary of x,000 licence fees. Two contrasting teams of 25, such as bus drivers ("the Ups" - hooray!) and underground train drivers ("the Downs" - awww!), were pitted against each other. Kerazzeeee stories were played on video tape to aforementioned teams, whose members each had to opine whether they were true or not through the medium of the keypad, with points being awarded to each team pro rata to the number of correct opinions. That is all.
Jeremy Beadle was one of the scriptwriters.
