Now that you mention it, the ONLY couples I seemed to see at the Venetian during this year's AVN were wasted porn chicks with not so good looking (or very old) guys.
Based on that observation alone, I reckon PW's must be the most wonderfully unsuperficial and non-judgemental people on this earth.
To an outside observer, their toleration of certain porn mopes within their nether regions confirms this view.
Although the girls were very well dressed, with nice shoes, handbags ....
