While crossreferencing the word I picked for today, I ran across this biggish word at infoplease, and knew that somebody was going to need it eventually.
Batrachomyomachia (pronounce Ba-trak'o-my'o-makia). A storm in a puddle; much ado about nothing. The word is the name of a mock heroic poem in Greek, supposed to be by Pigres of Caria, and means The Battle of the Frogs and Mice.
Now there is a word with a useful meaning that can be used to hush children and puzzle strong men!
