A group of Army staff officers are getting ready for a meeting.

While waiting for the coffee to finish brewing, the Colonel starts a conversation with his staff about his lack of sleep the previous evening. Apparently Mrs. Colonel was feeling a bit frisky, and dealing with her desires kept him from getting enough sleep.

He decides to pose a question to his staff: What percentage of sex is pleasure, and what percentage is work?

The junior Lieutenant responds "It's seventy five pecent pleasure and twenty five percent work, Sir."

The Captain says, "I believe its fifty fifty either way."

The Major is positve. "It's certainly twenty five percent pleasure and seventy five percent work."

At this point, the Colonel notices that the PFC making the coffee is grinning and shaking his head. The Colonel asks "Private, you've heard this discussion, what do you think about the question?"

"Sir", the Private responds, "It's surely one hundred percent pleasure."

The Colonel, intrigued, asks him why.

"Sir, if there was any work involved, the officers would have me doing it."

The room got real quiet.
