One day I found myself researching the best way to put up "no hunting or trespassing" signs in the commonwealth of Pennsylvania (hunting being the most common reason for trespassing given by 9 out of 10 trespassers). Lo and behold, there is a oft cited myth that these signs need to be signed. I figure go ahead and sign the dumb thing, illegible if you have to, just to ward off those that also tend to believe in magic. My friends had this sign in their dorm room as some type of joke. To this day, I don't know what that joke was, but I laughed like a got it, every time I saw it.
