The famous line ending the commercial PSA between action and adventure during the Superfriends. Ah, how simple it all seemed.
A young boy steps innocently steps off the sidewalk into the path of a speeding car. Suddenly, Superman appears, swoops up the surprised boy and returns him safely onto the sidewalk of his suburban neighborhood. "You know, you need to look both ways before you cross the street, you could've been hit by a car," Superman instructs. "Gosh, I didn't know," says the innocent young boy. "Well, now you know, and KNOWING IS HALF THE BATTLE," says Superman as he smiles and flies back up into the sky.
