Con. Law. Geek Alert!
In case you haven't already seen it, UCLA Law Professor Eugene Volokh is running an informal contest to come up with your own Amendment to the Constitution. It is not as easy as it sounds, especially given the cautionary advice that Prof. Volokh provides to would-be entrants. I have sent mine in (no, it does not repeal the condition that American Presidents be either natural born citizens or 227 years old) and I encourage you to have a go as well.
