This sign, submitted by David, looks remarkably similar to this one. And so does the guy holding it for that matter. I think we have a repeat offender on our hands. The "details in the bible" bit on this one is really my favorite, though it does not have quotations. Maybe the "while you are able" bit signifies a subconscious affinity for Calvinism?
I don't usually post the following: newspaper headlines, personal email, craigslist postings, unprofessional websites. I also tend to not crosspost things from other blogs, since I have so much unique material waiting for me to get to it.
Things I see a lot: silica gel "do not eat"; hair dryer labels; inside the bus "do not drill"; Wal-mart sign about IDs; coffee machine with "2" cup sizes; employees must "wash hands".
