In this "Barney & Friends" special about the art of good manners, a petulant Baby Bop blurts out orders without bothering to say "please" or "thank you," prompting Barney to explain the importance of using the "magic word." But Baby Bop really gets the point when her overactive imagination envisions a world that's overrun with rude people. As it turns out, being polite makes the planet a much happier place.
