There is a scene in the iconic 1962 film Lawrence of Arabia in which the protagonist -- T.E. Lawrence -- lights a cigarette and proceeds to nonchalantly extinguish the match between his thumb and his forefinger. Corporal William Potter looks on with a puzzled expression. When he thinks Lawrence is looking away, Potter surreptitiously tries to repeat the trick himself.
"Ooh, it damn well hurts!," he winces, frantically shaking his hand.
"Certainly it hurts," responds Lawrence, sagely.
