A 'colonial' air force, somewhere south of the equator, in Africa, and there is a war on .......
Officer Cadets on daily parade and drill practise. Gobby little drill corporal (known as 'Klinger' behind his back) taking the parade. Said corporal, during a lull in proceedings, thinking he is being smart, walks down the front row asking individuals, "Does you sister f**k?" Several answers of "Perhaps, Corporal!", "Yes, Corporal!" or "I don't know, Corporal!"
This continues until the corporal reaches a big, burly ex-army chap who is the holder of a gallantry medal:
Corporal - "Does your sister f**k?"
Big Bloke - "No, Corporal!"
Corporal - "Why the f**k not?"
Big Bloke - "Because she is f**king UGLY, Corporal!"
Assembled Cadets crease up, 'Klinger' has a crinkle, and the Cadets all have to take another run around the parade square several times. We eventually 'broke' 'Klinger' so that he didn't mess with us again.
