You've heard the type: They know everything. But how? How could some of these TV characters know things that took place when there was only one person around - and it wasn't them? Or sometimes they know other people's innermost thoughts and secrets before they're ever revealed. Some of these folks are dead and speaking from beyond the grave, some have never been seen by anyone and some are talking from a future perspective. We're not sure how it's possible, but it seems to happen a lot on television, so we're looking back at the best shows that feature omniscient characters (not necessarily narrators) from both today and yesteryear. You know you love them. Xoxo.
