Please explain "Lady Gaga" to me and my elderly wife →[More:]We just finished watching "Lady GaGa's" SNL performance from last night (on Tivo, of course, because who can stay up that late?) and we're really, really confused. Is she a performance artist? Some Meta-inside joke? We're not supposed to take her at face value, are we? Does "Poker Face" mean what I think it does? Please...to the youth of America and the world...explain this person to us. Also...she's not a dude, is she?
