Note to advertisers: be really careful who you pick to pitch your products.

Sure, you want a big name. You want convincing. You want sexy. But do you really want someone who doesn't even like your product? (Hint: no!)

Yesterday, Paris Hilton plead 'no contest' to one count of alcohol-related reckless driving -- she'll pay a fine and be on probation for 36 months. All this because she was really hungry (and drunk) and "wanted to have an In-N-Out burger."

Which all would be a juicy story, and par-for-the-course with the idle rich like Ms. Hilton. Except that she's a former spokesperson (spokesmodel?) for rival Carl's Jr., a unit of CKE Restaurants, Inc. (NYSE:CKR). There was so much egg (or was that hamburger grease?) on everyone's face, the incident made Business 2.0's list for dumbest moments in business.

I'll give this: you probably don't want your spokespeople drinking and driving. But if they do, and they're caught in the act and interviewed as to what was going on, wouldn't you want them to say, "I really wanted a Carl's Jr. burger?"

Pick your spokespeople like you pick your CEOs: make sure they love 'em a good ____ [your product goes here]. It will at least make for a good crawl on CNN. Any PR is good PR... right?
