Wow, Frag, you're so right. And when you're throwing out concepts at a client, seeing which ones they like, that's really the moment to legally vet and check the slogans. 'Cause before you go worrying about something silly like whether or not your client is happy, you really want to be thinking hard about copyright violation.
Here's a thought: There are hundreds of thousands of slogans out there. Many are not only copyrighted, but trademarked as well. If you stress about that while brainstorming, you're in the wrong business.
For heck's sake, we don't want to get into this here. Trademark and copyright law are complicated. And don't get me started about regional business usage. Yes, of course, mess with the Litigious Mouse and you're going to have your day in court, but there are far more pitfalls than that. None of which you should be stressing over while you don't even know what your client wants or likes.
