Superduperman, AKA Clark Bent, is a superhero, and secretly vice-office boy, that is called a creep by EVERYONE! But, when Bent changes, Superduperman arrives!
William M. Gaines created this as one of his first spoofs, and evenutally ran out of ideas for creating spoofs of these superheroes, and went on to making MAD what it is today. He started out by spoofing the stupid things in America, and then it went downhill from there. Now, MAD spoofs stuff such as Lady Gaga, Justin Bieber, and many more idiots. They also have a long history of lawsuits.
