A lieutenant, a major and a colonel were in the bar at the officer’s club, having a debate about sex: how much was pleasure and how much was work.
The lieutenant, just back from his honeymoon, said it was 75% pleasure and 25% work.
The major, who was getting up in age, said it was 50-50.
The colonel, who was ready for retirement, said it was 75% work and 25% pleasure.
They couldn’t come to an agreement, so they decided to ask go to the barracks and ask the sergeant on duty.
The sergeant told them it was 100% pleasure.
When the three officers asked him why, the sergeant said “Because if there was any work involved, the three of you would have me doing it for you!”
