6. The Wizard of Oz rolls off the tongue a lot easier than the man behind the curtain's 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." [mean joke, parents. first you have to spell that whole name, and by the time you've figured out how to spell it, everyone else has moved on to calling you pinhead.]
