New Urinal-Based Video Game Makes a Splash
Those who enjoy drinking beer, playing video games, and (oddly enough) peeing in urinals may be able to reach true nirvana after all. "Place to Pee" is a new video game that relies on a player's ability to hit sensors in a urinal to control game play. While this may seem extremely male-centric, don't worry, ladies, the game designers have thought of you too, and have designed a specialized paper cone for participation. Man, it's a bad day to be a janitor.

This came out of MIT a while ago, and it was called "Urine Control" (You're in control). http://web.media.mit.edu/~hayes/mas863/urinecontrol.html
I'm a male in my early 30s and I have a "bisected stream" issue like 80% of the time I take a leak standing up.
It must be the shape of the urethral opening, but I get the main stream and sometimes a secondary "side piddle", much like pouring water from a glass (some snakes down the side of the glass). Probably about 5% of the volume of the main stream.
This can result in some nasty surprises since you can't really feel it happening. You look down after taking a leak and notice "oh my, I just pissed all over my right pant leg". I've gotten into the habit of putting my right hand kind of to the side to block the side-piddle if it does happen. Better on your hand than on your pant leg.
YMMV, obviously. This has never been officially diagnosed by a doctor (not that big a deal, and I'm sure as shit not having surgery done to fix it), but it does happen.
With the first link, the chain is forged.
