One morning, in basic training, the drill sergeant came out and said he needed a volunteer for KP duty in the mess hall. After a minute of silence he pointed to a recruit and said, "You Volunteered!"

Panicking, the recruit said, "I didn't volunteer..."

The drill sergeant looked at him and said, "Were you drafted?"

"No, sir."

The drill sergeant smiled at him and said, "That's right! Therefore you volunteered."
