Related - that's kinda when peeing sitting shines - peeing half-asleep with lights off. All you gotta do is manage to locate the seat with your ass cheeks. Then just sit there, no need to aim, pay attention, have the light on so you can see (if you can't echolocate), but even if you can echolocate mistakes are common and yelling isn't far behind. You just sit there and it happens without getting proper awake.
