Better yet, use the EFF's Diceware list. It's easy to pick randomly from the list (just roll some dice) and the resulting passphrase won't have some of the issues a dictonary chosen one would have, like compound words causing entropy reductions. (EG if fire, truck, and firetruck are included in the dictionary as 3 separate words and you happen to get fire and truck in sequence as part of your passphrase the entropy of those two words is equivalent to the entropy of a single word! Not good.)

In a word-based password scheme, you are treating entire words, not characters, as units. The chance of fire, truck, and firetruck appearing in one password in that sequence, given a 10K word dictionary, is 1/(10K^3). The miniscule possibility of this speaks to the fact that there actually is a large entropy.
