butter beans and a ford f-250.. what do they have in common?

Yesterday, whilst driving home from MAL*WART i was behind this modern Ford F-250 that had this magnetic sign on the tailgate that said BUTTER BEANS in a rounded arial-ish font and the letters were all rotated at different angles that were all less than 20° or so from normal. Oddly though was that this was your typical redneck truck that had a lift kit on it. There seemed to be no brand name or any other marks that would identify this as some sort of advertisement and makes me wonder if the owner just simply has some sort of fetish for the legume in question. In hindsight, i shoulda snapped a picture from my phone, but i'm not sure it would have turned out too well. Anyways, if anyone wants to offer up a theory aside from the legume fetish, i'm certainly more than willing to entertain it.
