Church Signs...

So every week I pass a variety of churches and I often wonder, who comes up with all of the witty stuff that they put on their signs? Do people sit around at church and think of this crap? Or is there some website that they go to show off all of their wittiness?
I was driving by a church on my way home this weekend and I saw this quote, which I thought was super creative: exposure to the son, will keep you from getting burned.
Props to whomever thought that one up...it made me giggle and then think about the message.
