What ARE they teaching kids these days?  After last weekend’s Grammy Awards, a sad-but-true Twitter trend was born- people posting tweets asking, “Who is Paul McCartney?” No, unfortunately they weren’t tweeting in the form of Jeopardy! answers- these people seriously don’t know who Paul McCartney is.  Um, he was just in this little band, maybe you’ve heard of them…they’re called THE BEATLES?!
