An Army and Marine General were standing at adjacent urinals at the Pentagon. Both finish up at the same time. The Marine goes to the sink and washes his hands, the Army General just zips up and leaves. The Marine catches up and remarks "You know General, I noticed that you didn't wash your hands after going to the bathroom". "That's right General" replied the Army General. "Well you know General in the Marine Corps we train our officers to wash their hands after going to the bathroom". "Well in the Army General, we train our officers not to pee on their hands!"
