Allegedly an RAF Group Captain was about to start the morning briefing to his staff. While waiting for the coffee machine to finish its brewing, the Group Captain decided to pose a question to all assembled.
He explained that his wife had been a bit frisky the night before and he failed to get his usual amount of sound sleep. He posed the question of just how much of sex was "work" and how much of it was "pleasure?" A Wing Commander chimed in with 75-25% in favour of work. A Squadron Leader said it was 50-50%. A Flight Lieutenant responded with 25-75% in favour of pleasure, depending upon his state of inebriation at the time. There being no consensus, the Group Captain turned to the Corporal who was in charge of making the coffee.
What was his opinion? Without any hesitation, the young Corporal responded, "Sir, it has to be 100% pleasure."The Group Captain was surprised and, as you might guess, asked why? "Well, sir, if there was any work involved, the officers would have me doing it for them." The room fell dead silent.
