During all my sorting (which is still going on by the way) I found THIS awesome picture.
This isn't photoshopped or anything, I took this picture myself while I was working one day. (It's a pipe going in to an oil tank.) I have NO idea what happened that prompted someone to write this. I'll tell you what though, I was SO glad I had my camera in my truck because I knew no one would believe me otherwise.
P.S. Isn't it great that the "not" is underlined? Like someone might miss it otherwise?
