I always thought when you were out on the links and had to pee you yelled 'Fore!' and pissed in a bunker or on a tree. Well apparently that's not kosher and you need a UroClub (Putter Pisser sounds better) urine collection device. I'm not so sure what's so discreet about pissing down the shaft of a fake golf club, but whatever.
Just place an inconspicuous towel over your junk, unscrew the cap of the club disguised to look like a 7-iron, and whiz away--up to half a liter. When you're done, stick the leak-proof club back in your bag and take your next shot.
The questionable device costs $50 and doesn't hold enough if you've been following the rules of golf and drinking the whole game. And that's why I'll be sticking to the sand traps. They typically provide good cover, and you can even drop some kids off at the beach if you have to. But remember: if you do, stay classy and cover them up like a cat does.
Thanks Chris, and remind me to never shake your hand
