Open the top floor window and piss down the roof guttering. That's what I do when caught short.
Did this many times at uni because I was on the top floor and the bathroom was 2 floorsbelow me. Only when absolutely leathered though because there were houses oposite and I needed the drukeness to avoid worrying about getting arrested for indecent exposure.
