This is slightly offtopic but I find the vulgar example passwords amusing. I used to use a lot of vulgar language in my code but when you have to commit it and other people (e.g. your supervisor) read it, you have to be more careful.
God, I hate these, especially in API documentation. Come up with a simple example of how I might want to use your API. The relationship between fruit and bananas is much more clear than between foos and bazzes.
I usually try to make my passwords obscene if I suspect that they're being stored in something that can be reverted back to plain text, or if I suspect that someone may force me to give it to them (e.g., clueless IT team).
