It's a bird! It's a plane! It's ... a poopie diaper? Entertainment Tonight reports that Nicolas Cage, 41, and wife Alice Kim, 21, welcomed son Kal-el Coppola Cage Monday in New York. Yes, you read that right: The Oscar winner and comic book fanatic (he took his last name from superhero Luke Cage) has christened his offspring with Superman's Krpytonian moniker, thus assuring plenty of playground teasing from the likes of little Apple, Phinnaeus, Pilot Inspektor, Moxie CrimeFighter and Audio Science. Cage isn't the first celebrity to seek baby name inspiration from the comics: Director Kevin Smith named his daughter Harley Quinn, an appellation inspired by the Joker's homicidal moll.
