Who knew?

I was driving home from work today when I heard "YMCA" by the Village People on the radio, and it made me wonder something: how on earth did we not know they were gay at the time? I think everyone I knew was shocked when we found out. I mean, c'mon--the lyrics, the costumes, the mustaches...were we THAT sheltered in our little suburban world? (I think I know the answer to that.) And how is it if you play "YMCA" at a ballgame you're guaranteed to have everyone on their feet making the letters with their arms, even in the most conservative, un-gay-friendly towns in the States? There's probably a deep meaning in this somewhere.
