There are a few more, and I'm sure there's ones for other services, but these are the most common ones used in the Navy.
During my more recent stay with the Navy, I noticed that a lot of people (still) think it's funny to tell people who most certainly should know better to paint the centerline. This generally results in some tit bouncing around the boat trying to find the centerline until someone reminds him that it doesn't exist.
