I have answered this tough question in a past post found here http://www.supercodepoet.com/archives/2004/11/rules_man_you_g.html#comments.

Learn from the women in your life - use a stall.

I'm not sure if you're aware of this, Miss Wow, but urinating in a stall makes a very distinctive sound. It clues in your fellow bathroom goers that you are likely afraid of the urinal for some reason.

Plus, the urinal is so much faster. It is one of the benefits of being a male - peeing standing up. Why would I forsake that birthright?

Who you callin Miss?

Um, you would forsake it because everyone can see your urine?

Ahh, Miss Wow. It is clearly "Miss" because you show a clear lack of understanding of what the real issue here is. :)

So I'll help you become slightly more educated in the realities of the male bathroom urinal. In a typical configuration, there are two stalls and three urinals. In the nicer bathrooms, there are partitions between the urinals for at least a minimal amount of privacy (ie a view of anything you might not want to see have seen is hidden from view). But you can still see any urinal neighbor's face.

Thus the dilema: do you greet someone you know with a bit of superficial conversation, or keep silent?

Here are some simple rules to live by:

1. Never use the middle stall! Come back if all are occupied.
2. The only acceptable conversation is "How's it going?" or "Whatz up?"
3. The only acceptable replies are "Fine" or "Nothing"

Who is this secret women of your life?

I will amend my rules a slight bit:

If you are at the urinal with a person that is in your “Circle of Trust� then you can carry on a slightly longer conversation. This works well of you are both working on a problem and Mother Nature calls at the same time. You can discuss solutions during the little break. A stipulation to this rule is that the bathroom has to be empty except for you two; otherwise just simple pleasantries must be exchanged. This keeps each person above reproach.

My rules:
1) A one to two word greeting (hey, or what's up) is fine. Three words is over the limit (How's it going).
2) Conversation may resume at the sinks during hand washing.

I think it's essential to always run a quick calculation, determining precisely how the remaining urinals can be used. For instance, if, as is usually the case, there are three urinals, never use the center one. That forces someone to stand next to you. I always opt for the far urinals whenever possible, though I won't hesitate to stand next to someone, provided there is no other option.

proper urinal etiquette: wait until the other man is in the middle of his business. grab him by the shoulders from behind, and begin forcefully shaking back and forth. i think it's called "the sprinkler" or something similar. are there any girls reading this? is my wife reading this?

speaking of men's bathrooms, one very interesting phenomenon is the hand dryers with instructions scratched out: "push butt firmly....rub hands...under..arm.....stop...auto..at..alley" this could probably make it onto roadsideamerica. sorry for changing the subject. back to peepee.

final comment: in response to wow's suggestion that we use the stall...he is no man who sits to pee. or in the words of kung-pow, enter the fist, "but i AM a man! I GO PEE PEE STANDING UP!"

i have so amny comments on this, but a few years ago i came accross this helpful tool...it may be a game, but oh so helpful in learning...i thope this is the same thing that i came accross (my work computer won't let me open it)...anyway...here it is...flasharcade.com/game.php?urinal
