So CBS's go-to glowering, pontificating, closet-dwelling curmudgeon has never heard of Lady Gaga or Justin Bieber, and for some reason that deserves airtime on network television. Here Rooney posits a question: "If I'm so average American, how come that I've never heard of most of the musical groups that millions of other Americans apparently are listening to?" Really, Andy? The truth? You hit the nail on the head when you said "age," buddy. It's not a big deal. I'm just not sure why it baffles you so much that you're exhibiting signs of decrepitude. Up next, Rooney tries to put a VHS tape in a DVD player, tells his grandson his haircut makes him look like a girl, and screams at a potato chip for being "too contemporary."
