If I had a freeway billboard, what would it say?

Well I don’t frequently drive on freeways, so I honestly don’t think I’d see my billboard that often to really enjoy it, especially if it was on a freeway, because that would be one of the perks of having a billboard, pointing your billboard out to people who are driving with you. But not to the point that said people get annoyed with you and punch you every time you insist on going by your billboard. There has to be limits on that sort of behaviour. Now, I think that if you’re going to have something on a billboard it should either be profound or possibly a little bit stupid, or if you can get away with it somewhere in the middle . Having a wildly hilarious billboard on freeway runs the risk of unforeseen traffic accidents.  Now my somewhere in the middle billboard would comprise of simple font coloured black so it would be easy to read on a simple white background, the billboard would read ‘Lunacy by appointment only’. Now for the stupid yet funny billboard idea perhaps ‘abandon all hope ye who enter’ outside a school on test day.
