"Lawrence of Arabia" (1962)

[Lawrence has just extinguished a match between his thumb and forefinger. William Potter surreptitiously attempts the same]

William Potter: Ooh! It damn well 'urts!
T.E. Lawrence: Certainly it hurts.
William Potter: What's the trick then?
T.E. Lawrence: The trick, William Potter, is not minding that it hurts.
