1. Did you know the Comic Book Guy on The Simpsons has a name? It's Jeff Albertson. But that wasn't the decision of creator Matt Groening. "I was out of the room when [the writers] named him," he told MTV in 2007. "In my mind, 'Louis Lane' was his name, and he was obsessed and tormented by Lois Lane."

6. The Wizard of Oz rolls off the tongue a lot easier than his full name, Oscar Zoroaster Phadrig Isaac Norman Henkel Emmannuel Ambroise Diggs. From Frank Baum's Dorothy And the Wizard in Oz:

"It was a dreadfully long name to weigh down a poor innocent child, and one of the hardest lessons I ever learned was to remember my own name. When I grew up I just called myself O.Z., because the other initials were P-I-N-H-E-A-D; and that spelled 'pinhead,' which was a reflection on my intelligence."

7. Mr. Clean has a seldom-used first name—"Veritably." The name came from a "Give Mr. Clean a First Name" promotion in 1962.

8. In a deleted scene in the 2006 Curious George movie, The Man With the Yellow Hat's name was revealed as Ted Shackleford. (Since the scene was deleted, perhaps this doesn't count.)
