This one is likely to be more relatable for the guys than the gals, but we'll see. The bathrooms at work are laid out such that you open the door, walk down a little 5 foot hallway and then round the end (180 degree turn) to get to the urinals. Naturally this leads to a lot of go to the bathroom, turn the corner, almost run into the back of a guy. Obviously this is not the wisest of layouts but you get used to the concept and learn to round the corner a little more slowly depending on need. Anyway. I round the corner and there's a guy using the urinal so I turn away and move down the line. Now normally the brain takes in just enough information to tell the legs to not proceed forward and as little else as possible, but this time more manages to make it into my consious. I realize that both of this guy's arms are down at his side while he's using the urinal (auditory clues indicate he is actively using it). Now maybe I'm in a miniority and don't know it, but usually this sort of activity has at least one of my hands occupied. So now I've got this mental picture of a guy just letting it sail, pissing wherever the laws of hydrodynamics decide to send it. Maybe he's got really good aim, or maybe no one ever taught him, or maybe he's just pissed at the janitor.
