Sex vs Work and the Sergeant Major

At a command picnic, a bunch of officers were standing around talking. A Lieutenant said, "I think that making love is 80% fun and 20% work."

A Major responded by saying, "No, I think that making love is more work than that. I would say that it is 60% fun and 40% work."

Then a Colonel said, "No, making love is definitely way more work than that. I would say that it's more like 20% fun and 80% work."

They continued to discuss the matter for several minutes until a Sergeant-Major walked by. The officers called him over to ask his opinion.

The Colonel said, "Sgt-Maj, we're having a discussion, and we'd like your input. The Lieutenant says that making love is 80% fun and 20% work. The Major thinks that making love is 60% fun and 40% work. I say that making love is 20% fun and 80% work. What's your opinion?"

The Sgt-Maj scratched his chin and said, "Sir, I think you're all wrong. Making love must be 100% fun, because if there was any work involved, you'd have one of the troops doing it for you!"
