If you haven't heard, Twitter was ablaze during the Grammy's with kids trying to figure out who "Paul McCartney" was. The fact that one of the Beatles was rocking the show was completely beyond them. All they knew was that he was "hella-old". More after the jump.

Funny Or Die put together this funny fake documentary about the life of Paul McCartney as if these Twitter kids wrote it.  Give it shot and either feel old, or feel sorry for the stupid kids-you're probably good either way.
