The Shorter Oxford Dictionary is an excellent source of passwords.
supercalifragilisticexpialidocious works or me...oops : )
I've heard differently; that password-cracking programs have lists of many, many words in the language. The best ones are those that have 'special' characters mixed with letters and numbers, but using a '!' instead of a '1', or '$' instead of a 's' might not be quite strong enough for sites or applications where you really, REALLY want to keep the hackers out.
Any dictionary is an utterly disastrous source of passwords.
