Here's a link on Bush's campaign page where you create customized posters. Certain words are not allowed, but you can often get around that by using all caps and substituting zero for the O character. Other words you would think they would ban they haven't caught yet - like, well, I don't want to tip them off. And for obvious reasons, I guess, they haven't banned words like "Jesus", "God" and "Allah." The possibilities suggest themselves! Enjoy. I'm off to staple some of these to telephone poles.
