Three men were using the urinals in a public restroom. The first man finished relieving himself, zipped up, strolled to the sinks and proceeded to wash his hands, using plenty of soap and water and doing a splendidly thorough job. As he was drying his hands (with lots of paper towels), he loftily announced to no one in particular "At West Point, I learned to be clean and sanitary." The man then left the bathroom in a cloud of self-satisfaction.

The second gent zipped up, marched briskly to the sinks, and scrubbed his hands with much less soap and water than the first man, doing a splendidly thorough job nonetheless. As he was drying his hands (with only one paper towel), he severely announced to no one in particular, "At Annapolis, I learned to be clean and sanitary, but I ALSO learned to be thrifty and environmentally conscious." He then strode from the bathroom with a purposeful air.

The third man finished relieving himself, zipped up, and ambled past the sinks to the door, muttering to himself, "At the Air Force Academy, I learned not to pee on my hands."
