I'm not even sure I could manage it in my jeans (a new pair of raw denim that is still pretty stiff). I could get the buttons apart but then I would have to navigate the zig zag maze that is my boxer briefs' fly at which point it would probably be so squeezed on the sides that I wouldn't be able to pee anyways. Not to mention that I probably wouldn't be able to re-button them without undoing the top button.
Even with jeans and a zip fly (unless they are really high rise) I'd open the top...those zippers are sharp motherfuckers. Dress pants have much safer zippers and much more pliable material so I don't feel the need to unbutton.
