Most Linux distributions have a neat little program that can be installed called fortune. It will give a short little inspirational quote, a saying, poetry, a joke, etc. The pool of fortunes is over 16,000 with a base install on Debian Etch.

Now the interesting thing is that there is another fortune package called fortunes-off. Offcolor, offbeat, offensive. Use your imagination. Being immune to all manner of inappropriate material, I of course installed it, and lo and behold, the first "offensive" (and randomly chosen) quote was as follows:

"Then there are those who really do believe, but take very good care to separate their religion off in a separate part of their mind. They don't let clashing thoughts ever literally clash. Either they do it by only thinking about religion on Sunday, or they somehow manage to keep their religious thoughts separate from their scientific ones. Those are the ones I find least easy to understand. And then, of course, there are those who just aren't very bright."
