The picture I showed was of a famous sketch done in
The Frost Report (which came later), not TW3!
An quick summary of that sketch is below:-
Of all the send-up's that appeared on The Frost Report, the best remembered, and often held as representative of the shows style was the Marty Feldman/John Law penned sketch about class. This involved 6ft 5inch Cleese standing next to 5ft 8inch Barker who in turn stood next to 5ft 1inch Corbett, and using each man's height to illustrate their standing in society. Middle-Class Barker explains: 'I look up to him (Cleese) because he is upper class but I look down on him (Corbett) because he is lower class.' Corbett: 'I know my place.' The sketch lasted no more than a few minutes but remained in the memory for so long that some thirty or more years later Ronnie Barker came out of retirement to make an updated version for a TV special with Ronnie Corbett (John Cleese was unavailable so Stephen Fry stood in for him).
