From Wallace Shawn's dazzling and disturbing dystopian play Grasses of a Thousand Colors (2009):

You see, the reality is -- and those of you who are younger may find this terribly hard to believe, but it happens to be true -- the reality is that in the old, old days when I was growing up, people simply didn't think very much about their genitals. And they never talked about them. So you see, for me, the way things are now still seems astonishing -- I mean, the fact that people talk about their penises and vaginas in public, at dinner parties, in magazines and newspapers -- I can't get over it. Ha ha ha!
