I found this edition of Red and Rover in my local paper today (yes, some of us still get our paper delivered on real paper). As awesome as it is, Brian Bassett got it wrong! That quote is not by L. Frank Baum. It's from the screenplay of The Movie, so it was written by either Noel Langley, Florence Ryerson, or Edgar Allan Woolf (or possibly one of the eight other ultimately uncredited screenwriters and retained by the other three), nearly twenty years after Baum died and forty years after the book was published. Sadly, I've seen this and many other lines from The Movie credited to Baum on many online sources. I don't get why this is so hard to check, but nobody seems to want to do it, or care.
