LOL!
Don't take this next comment personally. I'm just venting and using your post as an example. "Charlie could of been" should be "Charlie could've been" or "Charlie could have been". I'm seeing "could of" and "would of" being used with ever more frequency across the board. I understand why the mistake is made (because of the pronunciation similarity). I don't really mean to be a spelling/grammar Nazi. Please forgive my forwardness.
