Peeing your pants, Chinese style

I've always though it would be easy to pee on your pants while using squat toilets. Well, an hour or so ago, I was tired and not being so careful, and actually peed on my pants while squating.. I had to sneak back to my room with a wet spot on the back (not front) of my pants. Usually mis-pees leave spots on the front of your pants or on a leg (if you are boy)...
