LOL - this is hilarious.
To the OP, I'm betting that you've never tried a device like this. If you had, I can't imagine this question even popping into your head.
Seriously? Yes. Seriously.
If I had a dime for every rock I've tried to cantilever myself out over just to avoid the "splash back" effect caused by my stream landing anywhere near my feet or my pant-legs (like it will if you just squat)...
It's an absolute GENIUS device, and I'd be loathe to take a ROAD trip without it, let alone head out into the great outdoors...
